But it is a change in behaviour, and what it makes worse it that it's an undocumented one. Users who have been doing the same thing for a decade suddenly find their old scripts are not working any more, and there it even a hint of what they do now. If we decide that such a change makes sense, then it must be explained and documented properly.

Why are you so ignorant? There are tools that are supposed to run on the build host (like mkimage or gen_eth_addr), and there are tools that are supposed to run on the target (like fw_*). Your "one size fits all" approach is broken. > > Seems this was not a fix, but introduced an error. Dp you agree to > > revert that commit? > > of course i disagree. this change is a fix in my mind. Please reconsider. This has been working for nearly a decade, and now it's broken. I want to see this fixed. If needed, by reverting the commit that broke it.

You are refering to this WIP patch: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/86236 It makes the fw_env tool Makefile similar to the imls Makefile and solves the errno inclusion problem reported by Detlev. I still think we need a third set of CC, CFLAGS, SRCS, etc defines for compiling tools running on the target. However, we probably can default to the combination CC+HOSTCFLAGS for most platforms.

Reverting is one option. I also tried Daniel Hobi's patch "tools/env: cleanup host build flags" and that worked for me.
