Hi everyone,
another option is to use the preprocessor
#ifdef ASSUME_PROPER_FORTRAN
...
#else /* less good one */
...
#endif /* ASSUME_PROPER_FORTRAN */
and set ASSUME_PROPER_FORTRAN as needed in the configure script.
Yet another way to fully fix this and similar issues is to
convert everything to ansi C, for example.
Have a great day,
Volodymyr
