At first glance these errors look like C++ vs. C syntax problems. I haven't looked at the scintilla code, but it would be my guess that the XS files is being compiled as C (this is the standard Makefile.PL behaviour) whereas Win32::GUI (for reasons that escape me) is built using a C++ compiler (see the override in Win32::GUI's Makefile.PL (sub xs_c) that builds .cpp files from the XS rather than .c files).
ARH! Yes, you are right. I've always wondered why win32-gui used a C++ compiler, as there is no C++ code.
I thin that (2) if preferable, and it is one of my longer-term goals to get Win32::GUI to use standard 'C' too.
I changed GUI.h (and GUI_MessageLoops.cpp) to be "C" safe. Cheers, jez.
