Bug #1937: Complaint about "__builtin_va_alist".

From: lupe@lupe-christoph.de Operating system: Solaris 7 PHP version: 3.0.12 PHP Bug Type: Compile Failure Bug description: Complaint about "__builtin_va_alist". gcc -g -O2 -O2 -I/opt/local/i386/include -I. -I. -I/opt/local/i386/imap/include -I/opt/local/i386/include -I/usr/X11R6/include/X11/magick -I/usr/openwin/include/X11 -I/opt/local/i386/mysql/include -I/opt/local/i386/postgres/include -I/usr/include -I/usr/local/include -I/opt/local/i386/include/xml -c main.c -o main.o main.c: In function `php3_printf': main.c:308: `__builtin_va_alist' undeclared (first use in this function) main.c:308: (Each undeclared identifier is reported only once main.c:308: for each function it appears in.) main.c: In function `php3_error': main.c:381: `__builtin_va_alist' undeclared (first use in this function) Using "gcc version egcs-2.91.57 19980901 (egcs-1.1 release)". The cause is the inclusion of "/usr/include" in the Makefile INCLUDE line. Dunno where this is generated by configure. /usr/include is always used by any Unix compiler I've seen so far, but GCC does not like seeing it before it's own include dir, for obvious reasons. Removing /usr/include from that line allows the compilation to proceed.
