Adam,
I don't know what version of Cygwin32 gcc you're using, but neither
the binary release (beta 19) nor Mumit Khan's egcs 1.1 for beta 19 behave
this way. They default to producing symbols with an underscore at the beginning,
which is the cdecl calling convention behavior.
Both fastcall and stdcall calling conventions append @<somenumber> to the end of their symbols, and fastcall prepends an @ symbol. the <somenumber> is actually
the number of bytes of the argument list.
To fix your problem, place this in all your source files that define or use
func():
void func( int arg1, int arg2, ... ) __attribute__ ((cdecl));
Make sure you use the exact argument list that you want; I just used examples
above.
