re PR fortran/31202 (Incorrect rounding generated for NINT)
PR fortran/31202
* f95-lang.c (gfc_init_builtin_functions): Defin builtins for
lround{f,,l} and llround{f,,l}.
* trans-intrinsic.c (build_fix_expr): Generate calls to the
{l,}round{f,,l} functions.
* intrinsics/c99_functions.c (roundl,lroundf,lround,lroundl,
llroundf,llround,llroundl): New functions.
* c99_protos.h (roundl,lroundf,lround,lroundl,llroundf,llround,
llroundl): New prototypes.
* configure.ac: Check for lroundf, lround, lroundl, llroundf,
llround and llroundl.
* configure: Regenerate.
* Makefile.in: Regenerate.
* config.h.in: Regenerate.
* gfortran.dg/nint_2.f90: New test.
