RC2 under FreeBSD 3.3 - undefined reference to `isfinite'?

Hi, I've been trying to compile PHP4 RC2 under FreeBSD 3.3, using: ./configure --with-mysql=/usr/local --with-gd=/usr/local --with-apache=/usr/local/custom/apache/apache_1.3.12 --disable-display-source I can build libphp4.a, but when I go to make Apache, I get: " gcc -I/usr/local/custom/zend/php-4.0RC2 -I/usr/local/custom/zend/php-4.0RC2/Zend -I/usr/local/custom/zend/php-4.0RC2/Zend -I/usr/lo cal/custom/zend/php-4.0RC2 -DUSE_EXPAT -I./lib/expat-lite -DNO_DL_NEEDED ./apaci -o httpd buildmark.o modules.o modules/stand ard/libstandard.a modules/php4/libphp4.a main/libmain.a ./os/unix/libos.a ap/libap.a lib/expat-lite/libexpat.a -R/usr/local/li b -R/usr/local/lib/mysql -rdynamic -L/usr/local/lib -L/usr/local/lib/mysql -Lmodules/php4 -L../modules/php4 -L../../modules/php4 -l modphp4 -lmysqlclient -lgd -lm -lcrypt -lcrypt modules/php4/libphp4.a(zend_operators.o): In function `is_numeric_string': /usr/local/custom/zend/php-4.0RC2/Zend/zend_operators.c(.text+0x2fe0): undefined reference to `isfinite' " The only place I can find 'isfinite' mentioned (admitadly with a simple fgrep) is in: Zend/zend_operators.c:#define finite(a) isfinite(a) /* HPUX 11 only has isfinite() */ Commenting out that line fixes the problem... I'd guess something thinks it's needed when it isn't? - The opening few lines from the ./configure show: shtool:echo:Warning: unable to determine terminal sequence for bold mode shtool:echo:Warning: unable to determine terminal sequence for bold mode checking for a BSD compatible install...
