Since Rational claims that it only works with Visual C++ 5.0 and 6.0,
I'm not surprised that it doesn't work with Cygwin. Purify is a very
intrusive tool (OCI and all that), and needs quite a bit of knowledge 
of runtime libs, and especially the memory manager used which for
Cygwin is dramatically different from MSVC's.

Perhaps speak with your customer rep at Rational?

Mumit
