Never messed with no steeenkin flags with the old MPE C code before.
It had always worked, at least up through 5.5.

But Goetz is correct, essentially.  You must declare _MPEXL_SOURCE
either in your ccopts variable or pass it as info to the C compiler,
even for plain old never-bothered-before C code.

It boils down to CTYPE.H.SYS, the end of which includes:

61     #  ifdef _MPEXL_SOURCE
62     #    ifndef __lint
63     #      define isascii(__c)            ((unsigned) (__c)<=0177)
64     #      define _toupper(__c)           ((__upshift)[__c]&0377)
65     #      define _tolower(__c)           ((__downshift)[__c]&0377)
66     #      define toascii(__c)            ((__c)&0177)
67     #    endif /* __lint */
68     #  endif /* _MPEXL_SOURCE */
69     #endif /* _CTYPE_INCLUDED */

I know this stuff worked before, I promise!  The only change was to a
departmental table (added a new one).

Anyway, thanks for the pointer Goetz.
