My own test-build of a native compiler on amd64 seemed to work fine. Do you have a sample build log of a failure with this patch? I was also able to successfully crossbuild gcc-4.4 to run on my powerpcspe system with this patch. Without the patch it tried to use "cc" as the amd64-to-powerpcspe compiler. The crossbuild was executed as follows: dpkg-buildpackage -us -uc -b -apowerpcspe The problem right now with a REVERSE_CROSS build is the following flow: ## Make initializes the variable by default: CC = cc ## The following if statement is not true (REVERSE_CROSS==yes) ifneq ($(REVERSE_CROSS),yes) ... endif ## Now we run configure configure-stamp: ../src/configure --host=... --build=... --target=... CC=$(CC) If you omit the "CC=" variable entirely (or give it an empty value) then the configure script makes appropriate guesses based on the --host, --build, and --target arguments.
