Author: tml Date: 2002-09-12 20:47:07 GMT 2002-09-13 Tor Lillqvist <tml@iki.fi> * Makefile.am (USE_INSTALLED_GLIB): Seems that the automake version used by Havoc doesn't recognize pkg_config_CFLAGS and pkg_config_LDFLAGS, thus failing builds on Win32 directly from the tarball. Set included_glib_includes and pkg_config_LDADD instead, then, like in the !USE_INSTALLED_GLIB branch. * findme.c (X_OK): If X_OK undefined, define as 1, always, not only if G_OS_WIN32, which is never defined here. Fixes a corner case on Win32 with MSYS and mingw where configure as included in the release tarball for some reason doesn't find unistd.h.
