Hmm, I did autoreconf, and aclocal.m4 didn't change. I looked at the pkg.m4 part of that file, and it does indeed use "AC_PATH_TOOL" -- but that doesn't seem to really do the proper thing for my cross-compilation test. Ok, to be more concrete, I was trying to use the mingw cross tools. I did: ./configure --host=x86_64-w64-mingw32 --build=`config.guess` of course since there isn't an "x86_64-w64-mingw32-pkg-config" program, instead it just uses the normal pkg-config, and this does the wrong thing (it _does_ emit a warning message, although it was rather cryptic until I started writing this post). It seems to me that the right thing in this case (no host-prefix tool is found) is simply to act as if pkg-config was not present at all, instead of using the non-host-prefixed version. -Miles -- `...the Soviet Union was sliding in to an economic collapse so comprehensive that in the end its factories produced not goods but bads: finished products less valuable than the raw materials they were made from.'
