dnl Find Fortran 90 modules inclusion flag. The module inclusion flag
|
||
|
|
dnl is stored in the cached variable ax_f90_modflag. An error is
|
||
|
|
dnl triggered if the flag cannot be found. Supported are the -I GNU
|
||
|
|
dnl compilers flag, the -M SUN compilers flag, and the -p Absoft Pro
|
||
|
|
dnl Fortran compiler flag.
