I think you need to add an effective-target check, because the new test
fails on aarch64/arm:
FAIL: gcc.dg/pr98099.c (test for excess errors)
Excess errors:
/gcc/testsuite/gcc.dg/pr98099.c:7:12: error: decimal floating-point
not supported for this target
/gcc/testsuite/gcc.dg/pr98099.c:9:1: error: decimal floating-point not
supported for this target
