Re: Issue with dllexport/dllimport inline function

[xclaesse@gmail.com]

Oh, that seems to be working now.

Still got a small issue, glib compiles with -Werror=missing-
prototypes: 

../foo.h:7:5: error: no previous prototype for ‘g_strcmp0’ [-
Werror=missing-prototypes]

I'm a bit lost with what the prototype would look like in this case.

I think `__attribute__((__dllexport__))` will be needed when building
with MSVC at least. Seems gcc, clang and msvc each wants a different
trick :/

Thanks,
Xavier Claessens.
