4.0.4 compiling problem

Hi there. I had already successfully compiled php3 and 4 in the past but never version php-4.0.4 stable. I'm using: Linux version 2.2.12-20 gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) php-4.0.4 After making a simple configure to build PHP as static apache module I get the next error: gcc -I. -I/root/packages/php-4.0.4/ext/standard -I/root/packages/php-4.0.4/main -I/root/packages/php-4.0.4 -I/root/packages/apache_1.3.12/src/include -I/root/packages/apache_1.3.12/src/os/unix -I/root/packages/php-4.0.4/Zend -I/root/packages/php-4.0.4/ext/mysql/libmysql -I/root/packages/php-4.0.4/ext/xml/expat/xmltok -I/root/packages/php-4.0.4/ext/xml/expat/xmlparse -I/root/packages/php-4.0.4/TSRM -DXML_BYTE_ORDER=12 -g -O2 -c microtime.c && touch microtime.lo microtime.c: In function `php_if_getrusage': microtime.c:97: storage size of `usg' isn't known microtime.c:100: `RUSAGE_SELF' undeclared (first use in this function) microtime.c:100: (Each undeclared identifier is reported only once microtime.c:100: for each function it appears in.) microtime.c:106: `RUSAGE_CHILDREN' undeclared (first use in this function) make[3]: *** [microtime.lo] Error 1 make[3]: Leaving directory `/root/packages/php-4.0.4/ext/standard' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/packages/php-4.0.4/ext/standard' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/packages/php-4.0.4/ext' make: *** [all-recursive] Error 1 Any ideas of what is happening?
