Subject: configure: improve pthread_sigmask detection.
X-Git-Tag: fio-3.36~1^2~1
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=1fa44a7ed981b36af3049dc99b5e8c2754bb51a0;p=fio.git

configure: improve pthread_sigmask detection.

On Windows system, pthread_sigmask is defined as a noop which will
trigger unused variable warning for sigmask.
By triggering the same warning in the configure script, we make
CONFIG_PTHREAD_SIGMASK undefined in the Windows msys2 build.
