PHP5.1.1 Pthreads issues on cross compilation

I have a problem that the PHP configure seems to automatically disable pthreads when I compile on cross platfrom. Host: i686-pentium-linux Target: ppc-powerquicc-linux More details about the target machine: PowerQuicc II MPC8248 My configure file is as follows: './configure' \ '--cache-file=config.cache' \ '--disable-debug' \ '--enable-memory-limit' \ '--enable-pic' \ '--enable-safe-mode' \ '--enable-sockets' \ '--enable-track-vars' \ '--enable-trans-sid' \ '--enable-wddx' \ '--sysconfdir=/home/yoav/export/etc/appWeb' \ '--with-exec-dir=/home/yoav/export/etc/appWeb/exec' \ '--with-regex=system' \ '--with-pear' \ '--with-xml' \ '--with-xmlrpc' \ '--enable-bcmath' \ '--enable-calendar' \ '--enable-force-cgi-redirect' \ '--enable-ftp' \ '--enable-inline-optimization' \ '--enable-magic-quotes' \ '--disable-rpath' \ '--with-zlib' \ '--with-db' \ '--enable-embed=shared' \ '--with-gnu-ld' \ '--prefix=/home/yoav/export/etc/php5' \ '--target=ppc-powerquicc-linux' \ '--enable-maintainer-zts' \ '--with-tsrm-pthreads' Using ZTS as an application I would like to use (AppWeb) required it and I must have a multi threaded version of PHP. Looking at the configure file it seems that PHP automatically chooses to disable pthreads once it detects it's a cross platform compilation. Thanks, Yoav.
