The GNU Fortran thing just means that Absoft sets some flags that g77/
gfortran set. No worries there.

I unfortunately can't replicate your issue with our Absoft compilers,
but we're at 9.2, so perhaps something has changed. The test code in
configure appears to have run correctly (according to your
config.log), but it doesn't look like it can read anything from the
file that is supposed to contain the sizeof result for the test.

Could you try to build and run the attached test code (should just
have to untar, run make, and run ./fsize) and let me know what the
result is? If all works properly, you should see something like:

     [21:23] brbarret_at_frood:ttyp3 ~/f77test% ./fsize
     size is 4
