This patch breaks about all the rules for robust autoconf tests:
1. Compile things using the compiler and the flags that the user chose,
not hardcoded ones.
2. Make sure you can clean up after yourself even if your code doesn't run
all the way through.
3. Don't execute programs you just compiled.

We are just checking a preprocessor define that we know will exist in
the SCO cc case, and this preprocessor define does NOT change based
on flags.
2. Make sure you can clean up after yourself even if your code doesn't run
all the way through.
I can, and I've tested it, because I blew the test a couple of times.
3. Don't execute programs you just compiled.
Why not?
It's only on the ONE platform, and how would you prefer the test be done?
