Note quite sure how to delve into exactly what the compiler is doing,
but doing some printing from the Makefile right before the compiler is
first called:

        @echo "Testing CFLAGS: $(CFLAGS)"
        @echo "Testing C:      $(C)"
        $(C) -DDINT -c ../Source/amd_aat.c -o amd_i_aat.o

I get

    Testing CFLAGS: -fPIC -wd1572 -mt_mpi -O3 -xHost -DUF_long=long
long -DUF_long_max=ULONG_MAX -DUF_long_id='%lld' -DNCHOLMOD
    Testing C:      mpicc -fPIC -wd1572 -mt_mpi -O3 -xHost
-DUF_long=long long -DUF_long_max=ULONG_MAX -DUF_long_id='%lld'
-DNCHOLMOD   -I../Include -I../../UFconfig
    mpicc -fPIC -wd1572 -mt_mpi -O3 -xHost -DUF_long=long long
-DUF_long_max=ULONG_MAX -DUF_long_id='"%lld"' -DNCHOLMOD
-I../Include -I../../UFconfig -DDINT -c ../Source/amd_aat.c -o
amd_i_aat.o
   icc: error #10236: File not found:  'long'

Double quotes don't seem to help. Changing 'long long' to 'long', it
builds fine.
