I just got this from a make build from Feb 28 15:29 GMT source:

/usr/src/gnu/lib/libstdc++/../../dist/toolchain/libiberty/strerror.c:8: config.h
: No such file or directory
 
Then I blew away everything in obj/gnu/lib,  and got the same after a make
obj dependall, so there aren't any old .depend files in gnu/lib. Any other
hints where to look? (That was a make build with the associated cleandir
anyway)

Cheers,

Patrick
