Subject: add macro version of ctype.h isascii function
X-Git-Tag: v1.1.11~57
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3d7e32d28dc9962e9efc1c317c5b44b5b2df3008;p=oweals%2Fmusl.git

add macro version of ctype.h isascii function

presumably internal code (ungetwc and fputwc) was written assuming a
macro implementation existed; otherwise use of isascii is just a
pessimization.
