At Tracker we want to mmap files using O_NOATIME. With GMappedFile this is at
the moment impossible. For that reason I added the constructor new_from_fd to
the GMappedFile type.

Previously, we were returning an empty buffer for all filenames
where fstat() gives a size of 0. But this is only appropriate
for regular files.
Also improve the documentation around this issue. Based on a
patch by Ryan Lortie.

In the case of an empty file, return NULL instead of "". This means
that the return result of g_mapped_file_get_contents() will always be
page-aligned.

* glib/gmappedfile.c (g_mapped_file_new): Report an error
if the file is too large. (#315275, Kjartan Maraas)
2005-07-01 Hans Breuer <hans@breuer.org>
* glib/gmessages.c : include <process.h> for getpid()
* glib/gmappedfile.c : include <io.h> for close() etc.
* glib/makefile.msc.in : add gmappedfile.obj

* glib/Makefile.am: libtool installs/uninstalls the import
library, no need to do it ourselves. Do still install/uninstall
the .def file, though.
* glib/gmappedfile.c: Add Win32 implementation.
(g_mapped_file_free): Don't mention writable shared mappings in
the doc comment. Free the GMappedFile struct.
* tests/mapping-test.c (main): No kill() or SIGUSR1 on Win32, use
a flag file instead to stop the child. Use g_usleep() instead of
sleep().
