I think this is related to the "Fortran merge."
Last night, Oracle MTT tests couldn't build the trunk (r26307) with
Intel compilers. Specifically, configure fails with
checking to see if Fortran compiler likes the C++ exception flags... no
configure: WARNING: C++ exception flags are different between the C
and Fortran compilers; this
configure script cannot currently handle this scenario. Either
disable C++ exception support or send mail to the Open MPI users list.
configure: error: *** Cannot continue
Looking in the config.log file, I see this:
configure:30518: checking to see if Fortran compiler likes the C++
configure:30538: icc -c -O3 -DNDEBUG -Wall -static-intel -m32
-finline-functions -fno-strict-aliasing -restrict -fexceptions
conftest.c(223): error: identifier "INTEGER" is undefined
Looks like the test is failing because configure is trying to compile
Fortran source code in a *.c file with the C compiler.
