Configuring with --enable-trans-sid causes make to barf

Hi, when compiling php4.03pl1 with this configure line: ./configure --with-apxs --with-mysql --with-pgsql --with-ftp --with-config-file-path=/etc/httpd/conf --with-exec-dir=/usr/bin --prefix=/usr --with-zlib --enable-sysvsem --enable-sysvshm --with-dbase --with-mhash --with-mcrypt --enable-bcmath --with-sybase-ct=/opt/sybase-11.9.2 --enable-versioning Everything is fine. However re-configuring with --enable-trans-sid to it and running make causes this error: [root@dell php-4.0.3pl1]#make Making all in Zend make[1]: Entering directory `/usr/src/php-4.0.3pl1/Zend' /bin/sh ../libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.. -DXML_BYTE_ORDER=12 -g -O2 -c zend-scanner.c In file included from /usr/include/errno.h:36, from zend-scanner.c:2619: /usr/include/bits/errno.h:25: linux/errno.h: No such file or directory make[1]: *** [zend-scanner.lo] Error 1 make[1]: Leaving directory `/usr/src/php-4.0.3pl1/Zend' make: *** [all-recursive] Error 1 Anyone help? Thanks. -- Richard Heyes
