re PR fortran/24519 (gfortran slow because of incomplete dependency checking)
2006-02-24 Paul Thomas <pault@gcc.gnu.org>
PR fortran/24519
* dependency.c (gfc_is_same_range): Correct typo.
(gfc_check_section_vs_section): Call gfc_is_same_range.
PR fortran/25395
* trans-common.c (add_equivalences): Add a new flag that is set when
an equivalence is seen that prevents more from being reset until the
start of a new traversal of the list, thus ensuring completion of
all the equivalences.
