Re: [patch, fortran] PR48976 INQUIRE with STREAM= not supported

[Tobias Burnus]

Dear Jerry,

thanks for the patch.However, I wonder about the following:
Will that be backward compatible with binaries compiled with GCC < 4.8 
or will that cause problems? I have the feeling that it is okay as the 
flag ("cf2") indicating whether "stream=" is present has still the same 
type and "iqstream" comes last in st_parameter_inquire and is only set 
if (cf2 & IOPARM_INQUIRE_HAS_STREAM).

Can confirm that there is no backward-compatibility issue? If there 
isn't, the patch is okay.

Tobias
