Subject: lib: Add static_assert() macro to _Static_assert()
X-Git-Tag: 2.4.0~3297
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2ae2d9ad6701073e02e40fae2973fc31360c6302;p=thirdparty%2Fdovecot%2Fcore.git

lib: Add static_assert() macro to _Static_assert()

We require C11 nowadays, so _Static_assert() should be supported.
static_assert() is nicer though, and it seems to be planned for C23.
