Fortran: prevent redundant integer division truncation warnings [PR108592]
gcc/fortran/ChangeLog:
PR fortran/108592
* arith.cc (gfc_arith_divide): Emit integer division truncation
warnings using gfc_warning instead of gfc_warning_now to prevent
redundant messages.
gcc/testsuite/ChangeLog:
PR fortran/108592
* gfortran.dg/pr108592.f90: New test.
