The choice of naming the flag "-pthreads" was perhaps not the best.  The
flag should work with UI threads, even though the name rings of "POSIX
threads".  I shamelessly picked it to be Makefile compatible with Linux.

If you're not using -pthreads (and I don't see how you could be on a UW2 
target) you need to set the right thing for the preprocessor, too.  I'm
guessing that a '-D_REENTRANT' is in order.

I don't see a problem on UW7 and don't have ready access to a UW2 system.
This test compiles and links without a problem.

Can you analyze what's in Intrinsic.h that it doesn't like?  If it would
help, I'll send you that file from a UW7 box for comparison.

Most of the maintainers won't grouse much about anything in the 100-200
line range.  It's the folks that do "I'm learning C++ and have written
a 12 zillion line program that fails.  Can you help debug it?" that get
ignored. :-)


Thanx for the testcase.   I'll poke at it later.
