MBS_SUPPORT is defined by the checks in mbsupport.h - noone should
be setting it on the command line.

I build gawk that way once in a blue moon just to test.

It may be that VMS and OS/2 don't have the MBS support, I'm not
sure.

Please see my other mail about why mbsupport.h cannot be renamed
dfaconfig.h and that a separate file is needed.

Thanks,
