From: Michael Forney <mforney@xxxxxxxxxxx> Prior to 2a4b472c3c, sys/signal.h was only included on OpenBSD (apart from two .c files). The POSIX standard location for this header is just <signal.h> and in fact, OpenBSD's signal.h includes sys/signal.h itself. Unconditionally including <sys/signal.h> on musl causes warnings for just about every source file: /usr/include/sys/signal.h:1:2: warning: #warning redirecting incorrect #include <sys/signal.h> to <signal.h> [-Wcpp] 1 | #warning redirecting incorrect #include <sys/signal.h> to <signal.h> | ^~~~~~~ Since there don't seem to be any platforms which require including <sys/signal.h> in addition to <signal.h>, and some platforms like Haiku lack it completely, just remove it. Tested building on OpenBSD after removing this include.
