Help from autoconf side would be good (it needs to know that gcc is used for compilation) I am not big fan of those wrappers, I think binutils should be able to auto-load the plugin of system installed compilers http://gcc.gnu.org/ml/gcc/2014-02/msg00128.html But osmeone needs to implement it, too... Also binutils can certainly be modified to output sane warning/error message when they see slim GCC files (those are easily detectable) and have no plugin. Honza > > Matthias
