rev3921 does not build for MacOSX

I get this:

Try this. I no longer have a Mac, so you'll have to tell us if it works.

problem, building C::B latest on freebsd 6.2


At the top of memorymappedfile.cpp you might add __WXMAC__ or whatever to:

#if defined(__WXGTK__)
    #include "errno.h"
#endif

Please tell me if that also worked.

It worked.
In memorymappedfile.cpp I added
at line 14:

#if defined(__WXGTK__) || defined(__WXMAC__)
    #include "errno.h"
#endif

and at line 222:

#elif defined(__BSD__) || defined(__DARWIN__)
   off_t size = lseek(hFile, 0, SEEK_END);
   lseek(hFile, 0, SEEK_SET);//go back to the start of the file
   if (-1 == size)
   {
      throw wxMemoryMappedInvalidFileSize();
   }
   return wxULongLong(size);   
#else

Thanks a lot. I hope this goes into the next rev.

Thanks to Tims S and bnilsson

I'll commit the fixes.
