SGI I cannot test, g95 indeed works, but NAG, SUN and ifort don't work.

What speaks against using   #include "..."  instead of  include '...' ?

With NAG f95 I'm really surprised that it works for you because it does
not do so here:

$ tar xfz ../preprocbug.tgz
$ f95 -V
NAGWare Fortran 95 compiler Release 5.1(346)
$ f95 -fpp hello.f
Error: hello.cmn: Invalid #line directive

g95 indeed works:

$ g95 -cpp hello.f

ifort as said does not:

$ ifort -cpp hello.f
fortcom: Warning: ./hello.cmn, line 1: Bad # preprocessor line
#if defined(USE_GFORTRAN)
$ ifort -v
Version 9.1

And SUN does not work neither:

$ sunf95 -V
sunf95: Sun Fortran 95 8.3 Linux_i386 Build35_2 2006/12/04
$ sunf95 -fpp hello.f

#if defined(USE_GFORTRAN)
