Most libraries included with packages install in /usr/local/lib (opposed to
/usr/lib). As for libraries that it may depend upon, as long as my GCC specs
file knows where to find libraries, I don't see a problem.

Not only is relocating easier, but it's the only current solution to this
particular situation. However, I FULLY agree that the CORRECT solution is to
"enhance" gcc, perhaps to have it honor a switch (e.g. -nostdlibdirs) which
will cause it to ignore the hard-coded standard default directories, i.e.
/usr/lib and /lib (which are one and the same in Cygwin).

Since I won't be submitting this proposed patch either, this is all just my
opinion as well...

Jon
