Canadian Cross building support. > Perhaps GCC has special > needs, but then again perhaps this indicates a deficiency in Autoconf. The deficiency is autoconf first trying host-prefixed tools then falling back to non-prefixed tools for cross-compilation. This behavior is not strict enough for Canadian Cross building, when you typically have strict naming conventions wrt. to build-, host- and target-tools. > When was this added to GCC and why? I don't know, but I am using similar macros for RTEMS for years (before autoconf-2.13), because autoconf's macros are not applicable to us. Ralf
