Remove cvs keywords from all files. 2010-09-21 04:08:53 +08:00			`dnl aclocal.m4`
Upgrade to Autoconf version 2.53. Replaced many custom macro calls with new or now-built-in versions. Make sure that all calls to AC_DEFINE have a third argument, for possible use of autoheader in the future. 2002-03-30 01:32:55 +08:00			`m4_include([config/ac_func_accept_argtypes.m4])`
Replace our hacked version of ax_pthread.m4 with latest upstream version. Our version was different from the upstream version in that we tried to use all possible pthread-related flags that the compiler accepts, rather than just the first one that works. That change was made in commit e48322a6d6cfce1ec52ab303441df329ddbc04d1, to work-around a bug affecting GCC versions 3.2 and below (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=8888), although we didn't realize that it was a GCC bug at the time. We hardly care about that old GCC versions anymore, so we no longer need that workaround. This fixes the macro for compilers that print warnings with the chosen flags. That's pretty annoying on its own right, but it also inconspicuously disabled thread-safety, because we refused to use any pthread-related flags if the compiler produced warnings. Max Filippov reported that problem when linking with uClibc and OpenSSL. The warnings-check was added because the workaround for the GCC bug caused warnings otherwise, so it's no longer needed either. We can just use the upstream version as is. If you really want to compile with GCC version 3.2 or older, you can still work-around it manually by setting PTHREAD_CFLAGS="-pthread -lpthread" manually on the configure command line. Backpatch to 9.5. I don't want to unnecessarily rock the boat on stable branches, but 9.5 seems like fair game. 2015-07-09 01:36:06 +08:00			`m4_include([config/ax_pthread.m4])`
