Are there any tests for Fortran 90 or Fortran 95?

[Dr. David Kirkby]

Are there any tests in autoconf that can be used to determine if a compiler 
support Fortran 90 or Fortran 95? I don't know Fortran myself, so writing one is 
out of the question for me. I was just wondering if there was anything like the 
equivalent of AC_PROG_CC_C99 whcih sets ac_cv_prog_cc_c99 to 'no' if one can't 
build C99 compliant code.

I must admit, reading the documentation would tend to suggest this is not so.
