[pushed] Fortran: keep

[FX <fxcoudert@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 494 bytes --]

Hi,

Fortran 2018 added some synonyms to the existing IEEE_CLASS_TYPE values, namely
IEEE_NEGATIVE_SUBNORMAL (which is the same as IEEE_NEGATIVE_DENORMAL)
and IEEE_POSITIVE_SUBNORMAL (same as IEEE_POSITIVE_DENORMAL). When they
were added to the C side, they were not kept in sync with the Fortran
part of the library. Thew new values are not used (yet), so it is
currently harmless, but better fix it.

I’ve pushed on master as obvious after testing on x86_64-pc-gnu-linux.

Subject: [PATCH] Fortran: keep values of IEEE_CLASS_TYPE in sync

Fortran 2018 added some synonyms to the existing values, namely
IEEE_NEGATIVE_SUBNORMAL (which is the same as IEEE_NEGATIVE_DENORMAL)
and IEEE_POSITIVE_SUBNORMAL (same as IEEE_POSITIVE_DENORMAL). When they
were added to the C side, they were not kept in sync with the Fortran
part of the library. Thew new values are not used (yet), so it is
currently harmless, but better fix it.
