v1.1.1... again

[Gerry Creager]

I'm trying to compile v 1.1.1 on a CentOS cluster, with a newly added 
gluster file system. We're running OpenMPI 1.4.1 and PGI 10.3.  Here's 
what I've done, so far:

module load pgi/10
module load openmpi/1.4.1/pgi/10.3/64
export cc=mpicc
export CC=mpiCC
export FC=mpif90
export F77=mpif90
export F90=mpif90
export CFLAGS="-O2"
export FFLAGS="-O2 -Msignextend"
export CPPFLAGS="-DpgiFortran"
./configure --prefix=/apps/pNetCDF/pgi-10-64 \
        --with-mpi=/apps/openmpi-1.4.1-pgi/ --enable-fortran

The fatal error is:
checking if Fortran "byte" is C "signed char"... configure: error: Could 
not compile conftest.c

Attached is the config.log for reference.  I'm betting it's something 
stupidly simple. However, I'm missing it right now.  Any suggestions 
appreciated.

Thanks, Gerry
