I made a simple test.c program:
#include <stdio.h>
#include <openssl/opensslv.h>
int main() {
printf("%s\n", OPENSSL_VERSION_TEXT);
}
which I compiled using gcc -v -o test test.c
gcc -v gives:
% gcc -v
Using built-in specs.

I didn't recompile this one with correct --with-local-prefix yet,
because it takes a bloody century (ok, a bit shorter) and it seems to
work fine. Same for my Linux setup with gcc-4.1.1-r1, which showed kind
of the same output.

Yep, 100% on that.

The less fuzzyness we need/require/introduce, the best our software
works on all kind of platforms ;)

My Solaris setup is hosed, so I can't test there. On Linux this works
flawlessly. Tomorrow I hope to start my Solaris prefix over again.
