Subject: use macros instead of inline functions in shgetc.h
X-Git-Tag: v0.8.8~34
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=26832d045f46e68b79277916edbad7512d253704;p=oweals%2Fmusl.git

use macros instead of inline functions in shgetc.h

at -Os optimization level, gcc refuses to inline these functions even
though the inlined code would roughly the same size as the function
call, and much faster. the easy solution is to make them into macros.
