Indeed it is. But IMHO, use of AC_PREFIX_DEFAULT should be strongly discouraged -- it imposes a default via the distributed configure script, which is likely to come as a surprise, perhaps even as a shock, to end users. More crucially, AIUI it overrides any local default set in a config.site, so any configure script using it will be comprehensively broken, for a default Win32 build on MinGW/MSYS. My suggestion was much less cavalier -- it merely sets a default which would be local to the host on which configure is executed; it is also the technique I use myself, on my Win32 box, to get a local default prefix with native Win32 semantics, (which many packages require), without the need to explicitly specify this individually for every package, or to hack individual configure scripts, to make them set an appropriate default: ac_default_prefix=`cd /usr/local; pwd -W` Regards, Keith. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
