Subject: libstdc++: Make preprocessor checks for __cpp_lib_atomic_wait consistent
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=670f5095e4aacc30099f6b73c1e67c06df76f36b;p=gcc.git

libstdc++: Make preprocessor checks for __cpp_lib_atomic_wait consistent

This changes some #ifdef checks to use #if instead.

libstdc++-v3/ChangeLog:

	* include/bits/atomic_timed_wait.h: Use #if instead of #ifdef.
	* include/bits/semaphore_base.h: Likewise.
	* include/std/version: Remove trailing whitespace.
