Subject: [PATCH] Fix some syntax errors (#1243)

* move signal.h inclusion outside of if-else block
not sure if this change is appropriate, we need to make sure SIG_IGN
is only set on POSIX targets. To verify this we might need to include
unistd.h,

* fix syntax error
this is often overlooked when compiling for normal platforms
