<cctype>: Do we still need to defend against isalnum/etc. macros? #259

Description

STL/stl/inc/cctype

Lines 21 to 35 in d0d724f

// remove any (improper) macro overrides
#undef isalnum
#undef isalpha
#undef isblank
#undef iscntrl
#undef isdigit
#undef isgraph
#undef islower
#undef isprint
#undef ispunct
#undef isspace
#undef isupper
#undef isxdigit
#undef tolower
#undef toupper

I suspect/hope that this code is no longer necessary. If it's still necessary, we should find out why, and see if the relevant code can be fixed.
