[PATCH 5/6] configure / meson: Move check for sys/signal.h to meson.build |
Date: |
Wed, 18 Nov 2020 18:10:51 +0100 |
This check can be done in a much shorter way in meson.build. And while
we're at it, rename the #define to HAVE_SYS_KCOV_H to match the other
HAVE_someheader_H symbols that we already have.
