Hi David,

That is a false assumption, I have been able to link a REAL win32 dll
against a cygwin application however linking a cygwin compiled dll
into a MSVC app is where you will come into troubles. This is because
neither cygwin's or ming's dlltool create dlls as specified by MS's
dll specification.

The name mangling is an issue from VC++ POV not the other way round.


My experience comes from building a win32 dll in Borland C++ builder
then having a simple console based cygwin gcc compiled app exercise
the dll's API - which btw was successful.
