Bug #4385: undefined reference to `isfinite'

From: everett@bentonrea.com Operating system: Linux RH 6.1 PHP version: 3.0.16 PHP Bug Type: Compile Failure Bug description: undefined reference to `isfinite' I get the follow error message when compiling apache:(bottom of message) ./configure --with-apache=../apache --disable-short-tags --with-mysql=../mysql No problems in PHP build. The error is related to a macro definition: 35: #ifndef HAVE_FINITE 36: #ifndef finite /* in case it's already a macro */ 37: #define finite(a) isfinite(a) /* HPUX 11 only has isfinite() */ 38: #endif 39: #else 40: #if HAVE_IEEEFP_H 41: #include <ieeefp.h> 42: #endif 43: #endif I'm not running on HPUX, I am running RH 6.1. If I comment out line 36 thru 39 it will compile and build with apache.
