Subject: [PATCH] Damien Carbery fixed bug #542

In SDL 1.2.13 sdl.m4 the AM_PATH_SDL function looks for sdl-config.
It sets the PATH:
 PATH="$prefix/bin:$prefix/usr/bin:$PATH"
but does not save the current PATH or restore the current PATH at the end.

This breaks the build on Solaris because we have GNU tools in another dir
(listed at the top of PATH) but non-GNU tools with the same names in
$prefix/bin. Later configure tests finds the non-GNU tools and quits in error
