php 5.0.3 and earlier used AC_C_BIGENDIAN during configuration to detect the endianness of the target system.  This autoconf macro is capable of detecting the endianness of many systems even when cross-compiling.

php 5.0.4 now uses AC_TRY_RUN instead, which means that it is no longer able to detect the endianness of a target, and it must instead be configured manually.

This makes it harder to configure php correctly when building for embedded systems, such as the Linksys nslu2, where this problem was noticed.

Yes, life is hard sometimes. If you can provide a reliable way to detect endianness when cross-compiling, feel free to send a patch.

what's wrong with AC_C_BIGENDIAN?
