After an aborted or clean build in a directory outside the gcc source tree,
"make distclean" is supposed to remove all configuration information. However,
that is not the case for at least one target (pdf). Using gcc-4.5.1 in my
build directory (as a bash user):
$ cd gcc_build
$ ../gcc-4.5.1/configure
... # nothing unusual
$ make pdf
... # nothing unusual except pdf target seems to
# result in LOTs of extra compilation
Come back the next day
$ export CC=/usr/local/bin/gcc-4.5.1
$ cd gcc_build
$ make distclean
$ ls -aCF
./ ../ fixincludes/
$ ../gcc-5.5.1/configure
... # nothing unusual
$ make pdf
make[1]: Entering directory `/usr/local/src/gcc_build'
make[2]: Entering directory `/usr/local/src/gcc_build'
make[2]: Leaving directory `/usr/local/src/gcc_build'
Configuring in ./fixincludes

configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and start
over
