Re: Windows, mkoctfile and DLLs

[Andy Adler]

I remember working for a company where I build
an image processing DLL which worked with the
company's product under NT, but failed during
unloading under 9x. I could never debug the
issue.

This problem sounds similar to what I saw.
This would indicate that it's not just a cygwin
problem.
