Make --with-threads=none mean, that we want thread support, but no default

Browse Source 
2001-10-31  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* configure.in: Make --with-threads=none mean, that we want thread
	support, but no default thread implementation. This also was the
	original intention, but disapeared around 1998... So it doesn't
	seem to be the most requested feature, but we went far to make it
	possible in the code, so I resurrected this feature.

	* INSTALL.in: Describe the --enable-gc-friendly, --disable-threads
	and --with-threads options of configure.

@ -46,6 +46,34 @@ A few of the more important ones:
* --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[ Defaults to the value given to --prefix ]
* --enable-gc-friendly When enabled all memory freed by the application,
but retained by GLib for performance reasons
is set to zero, thus making deployed garbage
collection or memory profiling tools detect
unlinked memory correctly. This will make GLib
slightly slower.
[ Disabled by default ]
* --disable-threads Do not compile GLib to be multi thread safe. GLib
will be slightly faster then. This is however not
recommended, as many programs rely on GLib being
multi thread safe.
[ Enabled by default ]
* --with-threads=[none/posix/dce/solaris/win32] Specify a thread
implementation to use.
* 'posix' and 'dce' can be used interchangeable
to mean the different versions of posix
threads. configure tries to find out, which
one is installed.
* 'solaris' uses the native Solaris thread
implementation.
* 'none' means that GLib will be thread safe,
but does not have a default thread
implementation. This has to be supplied to
g_thread_init() by the programmer.
[ Determined by configure by default ]
Options can be given to the compiler and linker by setting
environment variables before running configure. A few of the more
important ones:
