hi there,
i've run into an issue where $PATH doesn't get discarded during buildworld. is
this behavior to be expected? to reproduce do:
1) be sure /usr/local/bin comes *before* /usr/bin in your $PATH
2) ln -s /bin/cat /usr/local/bin/cc (some sh script would be better)
3) cd /usr/src ; make SRCCONF=/dev/null __MAKE_CONF=/dev/null buildworld
4) see how buildworld fails, because cat(1) gets invoked instead of cc(1).
... buildkernel on the other hand seems to be immune to such an issue.
The bootstrap stage needs *some* compiler on the host system to build
the (cross)compiler that is then used during the rest of buildworld (and
all of buildkernel). If you remove cc or c++ or libstdc++.so then you're
screwed.
As to whether the user's PATH should be honored for building the
bootstrap/cross/build-tools, I'd say yes.
If, however, the breakage is during the actual build-everything stage,
that would be a problem indeed.

Uli
