Subject: ctype.c: protect tiny C preprocessor constants
X-Git-Tag: v1.6.0.2~50
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c67b1fa349cc7b4341b32b9ef1c58a3821ce0830;p=git.git

ctype.c: protect tiny C preprocessor constants

Some platforms contaminate the preprocessor token namespace with their own
definition of SS without being asked.  Avoid getting hit by redefinition
warning messages by explicitly undef SS, AA and DD shorthand we use in this
table definition.
