Fixed bug #522

Mike Frysinger 2007-12-10 16:47:36 PST

it's much easier to manage .pc files for cross-compiling setups than it is for
random *-config scripts ... the cross-compiled pkg-config files can all be
easily/tightly controlled and separate from the host pkg-config files. the
*-config files however are to be found in $PATH and can easily pick the wrong
one.

can we get the sdl.m4 macro updated so that it checks for libsdl.pc first via
the standard PKG_CHECK_MODULES() m4 macro, and if that fails, fall back to the
normal sdl-config voodoo.
