When I do the -c bit I get this error:

Now am I suppose to compile the BitmapRsrc files into a BitmapRsrc.o
and then into my main program like the above compilation text. Because
this is where I get the errors regarding the above inline functions
which are defined in the BitmapRsrc.h file. The functions aren't even
in Neoslate.c so I don't get why it meantions that code. Now also in
the BitmapRsrc.h file there is the following:
#ifdef __cplusplus
extern "C"
{
#endif
All the inline functions are nested inside the above. I assume that
this is only for C++ compiling.
So any ideas ...
Thanks for any help,
Landon
