Isn't that supposed to always be defined in limits.h or is UCHAR_MAX not a standard macro?
Yes, it's supposed to be there. OTOH, so is limits.h, i.e. the HAVE_LIMITS_H test shouldn't be necessary either. So they're just sanity checks. But you're right, if UCHAR_MAX isn' defined, I was thinking the preprocessor would expand
#if UCHAR_MAX != 255
to
#if != 255
and then the error message would be incomprehensible. But unknown names in preprocessor conditionals actually get replaced by 0, and
#if 0 != 255
does just as well.
Sounds like a plan. I modify my local source and see if it affects anything.
It should work fine.
