Errno??

Hello, I am having a problem with compiling php. I am using the command # ./configure --with-mysql --with-xml --enable-track-vars --with-apache2=../httpd-2.0.45. After compiling everything, and issuing the make command, I am getting bunch of errors. /usr/local/src/php-4.3.1/ext/mysql/libmysql/my_delete.c:16: undefined reference to `errno' ext/mysql/libmysql/my_tempnam.o(.text+0x89):/usr/local/src/php-4.3.1/ext/mysql/libmysql/my_tempnam.c:108: more undefined references to `errno' follow collect2: ld returned 1 exit status make: *** [sapi/cgi/php] Error 1 Can somebody please explain what these errors are or what causes these errors and how to prevent them. Any help would be greatly appreciated. Btw, I am a total newbie to linux and php. So, please, guide me in the right path. Thanks Tobin
