Testsuite failures show that libfortran contains call to the c99 functions round
and roundf.  It's not safe to assume that the system runtime environment will be
fully c99 conforming (very few, if any, are).

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-05-05 11:37 -------
Confirmed, this is a bug in the Fortran front-end:
  /* We define there seperately as the fortran versions have different
     semantics (they return an integer type) */
  gfc_define_builtin ("__builtin_round", mfunc_double[0],
                      BUILT_IN_ROUND, "round", true);
  gfc_define_builtin ("__builtin_roundf", mfunc_float[0],
                      BUILT_IN_ROUNDF, "roundf", true);

Maybe the library should provide them but than again C99 has been out of almost 5 years now, 
providing basic functions as such as round should be required now for some new languages.

By the way, I can say glibc has C99 functions included since at least 2.2.5 which was released back in 
2002.

Irrelevant.  NetBSD doesn't use glibc.

I was just trying to make the point that glibc added the functions and was wondering why netbsd has 
not, that is all.  Maybe we should just document that gfortran requires a C99 math library to be present, 
I think that is a good idea.

And maybe we should fix gfortran so that it doesn't need c99. 
Personally, I think that's an even better idea :-)

On more thing, why has the bug in netbsd for adding these functions, round and roundf been ignored.
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=24252
In fact there is a patch in there to add them.

Well, it's more likely that it's just not been processed yet, there's
currently >3000 bugs outstanding.  I don't know what, if any, effort is
being put into making the C library C99 conforming [A quick search of
the mailing lists suggests that there is some activity, but it's
probably not an all-out push at this time].

Sadly NetBSD doesn't have as many folks triaging the bug database as GCC
does (and in some cases OS bugs are far harder to pin down, due to
subtle differences in HW).

In any case, that wouldn't affect NetBSD 1.6.x which is the last public
release.  Nor is it likely now to affect 2.0 when that comes out (since
the release branch has now been cut).

R.

This is a libfortran problem, not a front end one.
