src/sigs.c: Define "_BSD_SOURCE" and "__BSD_VISIBLE"
SIGWINCH isn't POSIX-compatible and causes a compile error on several platforms, such as OpenBSD: sigs.c: In function 'generic_hdlr': sigs.c:63: error: 'SIGWINCH' undeclared (first use in this function) sigs.c:63: error: (Each undeclared identifier is reported only once sigs.c:63: error: for each function it appears in.) sigs.c: In function 'sigs_init': sigs.c:97: error: 'SIGWINCH' undeclared (first use in this function) *** Error code 1 Define "_BSD_SOURCE" explicitly in this compilation unit to enforce definition of the "SIGWINCH" constant. Also, set "__BSD_VISIBLE" to 1 since FreeBSD doesn't honor "_BSD_SOURCE". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
