Subject: config.mk: improve feature test check
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=2d2175ff6f67e2bc85138d3f359d2f7580bcb754;p=dmenu.git

config.mk: improve feature test check

this fixes a crash on NetBSD because it requires -D_XOPEN_SOURCE (strdup, usleep).

thanks k0ga and stateless for reporting and fixing this issue!
