PHP 4.0 Bug #4767: configuration-parser.c and Zend/zend-parser.c break the HP ANSI C optimizer

From: bbrown@ibexa.com Operating system: HPUX 10.20 PHP version: 4.0.0 Release PHP Bug Type: Compile Failure Bug description: configuration-parser.c and Zend/zend-parser.c break the HP ANSI C optimizer If PHP is compiled with optimization on (-O, +O1, +O2, etc), HP's ANSI C compiler produces many internal errors when compiling configuration-parser.c and Zend/zend-parser.c, probably resulting in incorrect output. The compiler requests that the files be compiled without optimization. I turned on optimization by setting the CFLAGS environment variable prior to running configure. Obviously, this is probably a compiler limitation. I would prefer that files be optimized whenever possible. Would it be possible to either work around this limitation (perhaps by breaking up the file), or selectively turning off optimization for these files in the Makefile?
