I am still seeing failures.  I will investigate and let you know
when I have more info.  Still failing are:

gfortran.dg/c_char_tests.f03
gfortran.dg/c_kind_params.f90
gfortran.dg/value_6.f03

The only difference is that c_kind_params.f90 was failing in all modes,
now it passes in 64 bit mode and fails in 32 bit mode.

c_kind_params.f90 in 32 bit mode seems to be failing to compile:

FAIL: gfortran.dg/c_kind_params.f90  -O0  (test for excess errors)
Excess errors:
/proj/opensrc/nightly/src/trunk/gcc/testsuite/gfortran.dg/c_kinds.c:13: error: e

/proj/opensrc/nightly/src/trunk/gcc/testsuite/gfortran.dg/c_kinds.c:34: error: (
Each undeclared identifier is reported only once
(and more)

value_6.f03 and c_char_tests.f03 are aborting during execution.
