Original commit message from CVS: * gst/gstvalue.c: (gst_greatest_common_divisor): use ints and return ints, fractions only use ints, too, so this avoids accidently casting multiplications to unsigned (gst_value_lcopy_fraction): it's ints, not uint32 (gst_value_set_fraction): disallow minint, multiplying and negation are broken with it (gst_value_fraction_multiply): fix to make large numbers work and get rid of the assumption that the multiplication of two ints fits an int64 - dunno if that's true for all systems * testsuite/caps/Makefile.am: * testsuite/caps/fraction-multiply-and-zero.c: (check_multiplication), (check_equal), (zero_test), (main): add tests for all the stuff above * testsuite/caps/value_compare.c: (test1): fix comment * tests/.cvsignore: * testsuite/caps/.cvsignore: * testsuite/debug/.cvsignore: * testsuite/dlopen/.cvsignore: * testsuite/states/.cvsignore: get up to date
