I agree.
For the benefit of gcc-patches, it was pointed out on gcc-help that the
description of the default directory used by --with-gxx-include-dir is
incorrect. The actual default is computed by a complex bit of configury
code, so stating it clearly -- let alone keeping it up to date -- in the
manual is hard. If you don't care, use the default; if you do care, you
ought not to rely on the default.
I checked in this patch to eliminate the false information, in favor of
vaguer words along the lines that Ian suggested, after testing that I
could still build the documentation and that it looked OK.
