source: scripts/patches/gcc-3.4.1-fix_configure_for_target_native.patch@ 643f8be

Submitted By: Ryan Oliver (ryan dot oliver at pha dot com dot au)
Origin: Ryan Oliver
Date: 2004-07-15
Initial Package Version: 3.4.1 (problem exists through 3.3 series)
Description: There are issues with configure when attempting to cross-compile
        a native gcc for target. During the last stage of make configure-host,
        where host = target, the configury doesn't check if host != build.
        Therefore it assumes that the build is a native build and performs
         binutils feature checks using either 
        a) what the native compiler we are building would normally use.
           If a target-native binutils has already been built with the same
           prefix, this is the binutils which is used which of course will not
           work on host
        b) the host os's assembler/linker/nm/as
        which leads to bogus results.
        This patch fixes this behaviour, so that if host = target and 
        host != build the cross tools will be used for feature checks.
