I am not a gcc or gcc++ expert. I can offer the following
observation, but don't ask me what it means. gcc is a major
project in its own right, and I do not know the ins-and-outs
of it.
In your logfile, you have the sequence:
===> gnu/lib/libstdc++
sed -e ...etc... > strstream-fixed.cc
rm -f .depend
mkdep -f .depend -a -DIN_GLIBCPP_V3 -DHAVE_CONFIG_H
-I/src/gnu/lib/libstdc++
-I/src/gnu/lib/libstdc++/../../../contrib/libstdc++/libsupc++
-I/src/gnu/lib/libstdc++/../../../contrib/gcc
/src/gnu/lib/libstdc++/../../../contrib/libstdc++/libmath/nan.c
...etc...
mkdep -f .depend -a
/src/gnu/lib/libstdc++/../../../contrib/libstdc++/src/bitset.cc
...etc...
The second one does not have the -DIN_GLIBCPP_V3 -DHAVE_CONFIG_H
or the three settings of -I. In a logfile of one of my own
buildworlds, both of those mkdep's seem to start out with the same
set of options. I expect the missing options are significant, but
I do not know why they would be missing, or what to do about them.
