Perhaps a gcc guru will take pity on me and explain what's going on here?
I know, theoretically, the answer is in the source code somewhere, but since
I've never read gcc source code before, I'd probably just end up horribly
confused.

Below, gcc-search-dirs.sh is a script which calls "gcc -print-search-dirs",
splits the output of the libraries section one-per-line, and then either
flags the dir as nonexistant, or canonicalizes it by doing "cd $dir && pwd".

As you can see, gcc tries to search many nonexistant pathes, and makes no
mention of /lib/w32api, which it *does* search for libraries

Help?!?

Thanks,

Max.
