malloc and free mixing in VC++ and cygwin

Maybe. :)
More precisly, can `malloc' be used to allocate memory in cygwin
and `free' be used in VC to free the cygwin-allocated memory?
No -- they use different memory schemes.
However, that doesn't mean that you can't have one environment
allocate memory, and have the other free it -- you just can't
use the C runtime functions.
The Win32 functions CoTaskMemAlloc() and CoTaskMemFree() can
be used to allocate/free memory between 2 otherwise incompatible
memory schemes. I suspect that most of the other Win32 memory
functions (GlobalAlloc/GlobalFree, etc.) could also be used
to do this as well.
