[Bug testsuite/36443] [4.3/4.4 Regression]: HOSTCC doesn't work with installed gcc

[janis at gcc dot gnu dot org]

------- Comment #51 from janis at gcc dot gnu dot org  2009-02-06 19:30 -------
Mark pointed out way back in comment #9 that GCC used to effectively do the
same thing by searching the install directory even without GCC_EXEC_PREFIX.  I
understand that setting it makes people nervous, but I haven't seen any
specific evidence that setting it is actually a problem.  I often reuse an
existing install directory, and if there were problems with picking up GCC
components from GCC_EXEC_PREFIX during testing then I would have seen failures
from new tests.

Rob, you haven't convinced me that there is a problem.  I'd want to see
specifics, like building a particular revision and then running a particular
test using

  make -k RUNTESTFLAGS="... xx.exp=testname.c" check

I posted a patch last week that cleans things up a bit by setting
GCC_EXEC_PREFIX in one place and switching it back again for running $HOSTCC;
