* Makefile.am: Don't distribute glibconfig.h.win32.in, but
glibconfig.h.win32. Generate it when making a dist. Also generate
makefile.msc and config.h.win32 from corresponding .in files when
making dist.
* configure.in: Also substitute @GLIB_INTERFACE_AGE@ and
@GLIB_BINARY_AGE@ (needed in config.h.win32).
* glibconfig.h.win32.in: Use static mutex structure and initial
value corresponding to the 1999-04-07 snapshot of pthreads-win32.
* tests/Makefile.am: Distribute makefile.msc. Generate it when
making dist.
* tests/makefile.msc.in: New file.
* tests/node-test.c: Include <stdlib.h> for exit().
