mixing C code from different compilers can be problematic.

if you want your extension modules to run with the windows binary
versions built by enterpriseDB, you'll need to use VisualC (plain C, no
C++), even the free express version is fine for this.

you could, in theory, setup a cross compile environment on Linux that
would let you use gcc to build both postgres and your extensions, but
then you'd be dealing with your own build of Postgres for Windows.
Also, setting up that environment would probably take a lot of
tinkering, and PostgreSQL on Windows with GCC is not considered a
supported platform at present (although people do successfully build it)

OK, thank you. Then I believe I have to go with a Wine-VisualC setup for that.

Thanks,
Daniel Migowski
