Bug #: 54279
Summary: first stage build with g++ fails with "." as the first
component of $PATH
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other

This build failure is a likely result of the recent change to compile GCC with
the C++ compiler during the first stage.
1. I have "." on $PATH.
2. In one build of the latest GCC trunk, I specify
CC=/usr/bin/gcc and CXX=/usr/bin/g++ and everything
works.
3. In another build, I don't specify CC or CXX.
Therefore they default to 'gcc' and 'g++'.
This fails:
g++: error trying to exec 'cc1plus': execvp: No such file or directory
If I remove "." from $PATH then the configuration in 3 will build.
The problem is that there is a g++ executable under the
built gcc directory, but cc1plus and other g++ component
parts haven't been built yet.
