It may be that VMS and OS/2 don't have the MBS support
VMS and OS/2 both have MBS support, as far as I can see. Certainly OpenVMS does.
Gawk's ChangeLogs suggest that mbsupport.h is needed only to support a port of Gawk to VAX C circa 2004, one where Pat Rankin ran into a problem with VAX C. This predates the gawk git first checkin, and predates bug-gawk, so I don't know what the problem was -- all I know is the bit of info that's in the Gawk changelogs. However, whatever the problem was, it should be possible to work around it without affecting dfa.c, and dfa.c should be able to be consistent about simply using MB_CUR_MAX to test whether we're in a unibyte locale.
I'll look into writing patches for that, one for grep (which affects dfa.c), one for gawk (which will use the same patches to dfa.c).
