[Bug libfortran/23356] New: FLT_EVAL_METHOD not defined on openbsd3.4

[fxcoudert at gcc dot gnu dot org]

On openbsd3.4, there is no FLT_EVAL_METHOD in the standard includes, so we
should think of something to do when it's not available:

This is weird as built just fine on openbsd3.1.

Well, the only reference to openbsd I found in gcc-testresults are some mails
from you, with openbsd3.1 but without gfortran. I just checked in openbsd3.1
source that there is no FLT_EVAL_METHOD defined (and on the production
openbsd3.4 I have access too, there's none too), so I mark this bug as confirmed.

Andrew Pinski pointed out that the problem is due to the setting of USER_H in
config/t-openbsd to an empty string.  That is most likely incorrect.

(The only other target which tries to set USER_H at all it i386-netware, and
that one is probably also wrong.)

Well, if nobody is interested in this, closing accordingly.

[Bug target/23356] FLT_EVAL_METHOD not defined on openbsd3.4

------- Comment #5 from espie at nerim dot net  2005-10-13 11:11 -------
I added FLT_EVAL_METHOD to OpenBSD's math.h in january 2005.
Currently, all releases up to OpenBSD 3.5 have been discontinued.
OpenBSD 3.6 reaches end-of-life in a few months.

As far as OpenBSD is concerned, this bug is not important: neither 3.7,
nor 3.8, nor -current are affected.

It might bite some other system.

As far as I'm concerned, this is a generic issue with Linux-centric configure.
Everything is often set up to either assume no C99, or full C99 compliance, and
there are still systems in-between (to wit, libstdc++ all-or-nothing locale
approach).
