glib/gstrfuncs.c
Tor Lillqvist a6149403de removed dummy structure definitions for struct _GCache, _GTree, _GTimer, 
Tue Oct 27 03:00:50 1998  Tim Janik  <timj@gtk.org>

        * glib.h: removed dummy structure definitions for struct _GCache,
        _GTree, _GTimer, _GMemChunk, _GListAllocator and _GStringChunk.

        * gutils.c: implement glib's inline functions _after_ all include
        statements have been processed.
        removed Tor's MAXPATHLEN check since there already was one supplied
        further down in this file.
        (LibMain): special cased the #ifdef __LCC__ case for NATIVE_WIN32,
        since lcc maybe used on other platforms as well. why in hell is this
        stuff required?
        (g_get_any_init): for windows, if the user name is supplied, use it as
        realname also.
        in general, if there is no homedir specified, use the tmpdir that
        we already figured.

        * gtimer.c (g_timer_elapsed): changed a g_assert() statement to
        g_return_if_fail().

        * applied glib-tml-981020-0.patch for WIN32 portability, added some
        comments and g_return_if_fail() statements, minor indentation fixes.
        ChangeLog entry from Tor Lillqvist is appended.

        * glib.h (struct dirent): use lower case structure members.

        * glib.h:
        * makefile.lcc:
        * makefile.msc:
        s/COMPILING_GLIB/GLIB_COMPILATION/

1998-10-20: Tor Lillqvist <tml@iki.fi>

        * README.win32 glib.def gmodule.def
        * glibconfig.h.win32 gmodule/gmoduleconf.h.win32:
        New files for the Windows port. The .def files list exported
        symbols for the Microsoft linker and compatibles.

        * configure.in:
        Added checks for some platform-dependent headers: pwd.h sys/param.h
        sys/select.h sys/time.h sys/times.h unistd.h, and the function lstat.

        * gerror.c:
        Conditionalized inclusion of system-dependent headers. Changes
        for Windows: no gdb to do a stack trace. Just call abort().

        * glib.h:
        Changes for Windows:

        Added macros G_DIR_SEPARATOR, G_DIR_SEPARATOR_S for
        platform-dependent file name syntax elements. Added macros
        G_SEARCHPATH_SEPARATOR, G_SEARCHPATH_SEPARATOR_S for
        platform-dependent search path syntax conventions.

        Added pragmas for Microsoft C to make it more pedantic.

        Marked GLib's global variables for export from DLL.

        Added the function g_strescape that escapes backslashes.

        Added functions g_path_is_absolute and g_path_skip_root to
        handle platform-dependent file name syntax.

        Added the function g_getenv that expands environment variables
        that contain references to other environment variables, as is
        typical on Windows NT.

        Added the GIOChannel structure which is used to encapsulate the
        IPC mechanism used by the GIMP's plug-ins, and possibly other
        things later. On Unix a GIOChannel encapsulates just a file
        descriptor. On Windows it contains a file handle from _pipe() and a
        few other things related to the implementation of gdk_input_add
        and GIMP plug-in communication. Subject to change.

        Removed duplicate declarations of the version variables.

        For the Microsoft compiler, declare own implementation of
        ftruncate and the <dirent.h> functions.

        * gmem.c:
        Define a symbolic name  for the profiling table size.

        * gmessages.c:
        Conditionalized inclusion of unistd.h. On Windows, output using
        stdio to stdout.

        * gscanner.c:
        Conditionalized inclusion of unistd.h. Added changes for
        Microsoft C. Added CR to the skipped character set. Added small
        workaround for MSC compiler bug in g_scanner_cur_value.

        * gstrfuncs.c:
        Added the function g_strescape, which escapes the backslash
        character. Needed especially when printing Windows filenames.

        * gtimer.c:
        Conditionalized inclusion of unistd.h and sys/time.h. Added
        implementations for Windows.

        * gutils.c:
        Conditionalized inclusion of platform-dependent headers. Use
        the platform-independent file name syntax macros.
        Conditionalize code on platform-dependent features. Added the
        functions g_path_is_absolute g_path_skip_root and g_getenv.
        Added the GIOChannel-related functions. Added
        compiler-dependent Unix compatibility functions for Windows.

        * makefile.lcc makefile.msc:
        New files. Compiler-specific makefiles for LCC-Win32 and
        Microsoft C. Only Microsoft C is actually supported currently.

        * testglib.c:
        Added pathname check cases for Windows. Added workaround for
        bug in the Microsoft runtime library. Improved some tests a bit.

Tue Oct 27 04:00:11 1998  Tim Janik  <timj@gtk.org>

        * testgmodule.c (main): changed the #ifdef WIN32 test to NATIVE_WIN32,
        this needs to be more constistent throughout the code, do we go for
        NATIVE_WIN32 or WIN32?

        * gmodule.c (LibMain): special cased the #ifdef __LCC__ case for
        NATIVE_WIN32, since lcc maybe used on other platforms as well.
        * libgplugin_a.c (LibMain):
        * libgplugin_b.c (LibMain):
        likewise. not sure i like this special requirement for lcc in here.

        * gmodule-dl.c (_g_module_build_path):
        feature empty "" directories and prepend the module name with "lib".

        * gmodule-dld.c (_g_module_build_path):
        * gmodule-win32.c (_g_module_build_path):
        feature empty "" directories.

        * we need some more magic in the _g_module_build_path variants
        so we don't append/prepend lib and .so, .sl or .dll for those names
        that already contain it.

        * applied patch from Tor Lillqvist for g_module_build_path() and
        windows support.

1998-10-20: Tor Lillqvist <tml@iki.fi>

        * gmodule/gmodule-win32.c:
        New file.

        * gmodule/gmodule.c gmodule/gmodule.h:
        Added the funcion g_module_build_path that builds the path to
        a module file, decorating the name according to the system's
        conventions.  Added the Windows implementation.

        * gmodule/libgplugin_a.c gmodule/libgplugin_b.c:
        Added LibMain for LCC-Win32.

        * gmodule/testgmodule.c:
        Handle Windows dll names.
