Does anyone know of any tools that ease the problem of porting fortran
code across many platforms, for code that uses extensions to Fortran77?
For example, hex data statements, some keywords in open statements, etc.
differ from platform to platform. e.g. a hex data statement is

      DATA J/Z12345678/     on VSFORTRAN (IBM)
      DATA J/'12345678'X/   on VAX
      DATA J/Z'12345678'/   on NeXT

One would like only a single master file, which has statements for all
platforms, and preprocessors for conditionally compiling statements
on each target platform.

In C, there are compiler directives (#if, #else, etc) for this.
Anyone have a method, or commercial product, for doing this to fortran?
