Janis,
   Yes, doesn't it need something like...

# Skip these tests for targets that don't support this extension.
if { ![check_effective_target_dfp] } {
    return;
}

which is in testsuite/gcc.dg/dfp/dfp.exp. I find...

grep -R check_effective_target_dfp testsuite | grep ".exp" | grep -v svn | grep -v Change
testsuite/g++.dg/dfp/dfp.exp:if { ![check_effective_target_dfp] } {
testsuite/g++.dg/dfp/dfp.exp:if { ![check_effective_target_dfprt] } {
testsuite/gcc.dg/dfp/dfp.exp:if { ![check_effective_target_dfp] } {
testsuite/gcc.dg/dfp/dfp.exp:if { ![check_effective_target_dfprt] } {
testsuite/gcc.misc-tests/dectest.exp:if { ![check_effective_target_dfp] } {
testsuite/lib/c-compat.exp:    set compat_have_dfp [check_effective_target_dfprt_nocache]
testsuite/lib/c-compat.exp:	set compat_have_dfp [check_effective_target_dfprt_nocache]
testsuite/lib/target-supports.exp:proc check_effective_target_dfp_nocache { } {
testsuite/lib/target-supports.exp:    verbose "check_effective_target_dfp_nocache: compiling source" 2
testsuite/lib/target-supports.exp:    verbose "check_effective_target_dfp_nocache: returning $ret" 2
testsuite/lib/target-supports.exp:proc check_effective_target_dfprt_nocache { } {
testsuite/lib/target-supports.exp:proc check_effective_target_dfp { } {
testsuite/lib/target-supports.exp:	check_effective_target_dfp_nocache
testsuite/lib/target-supports.exp:proc check_effective_target_dfprt { } {
testsuite/lib/target-supports.exp:	check_effective_target_dfprt_nocache

but for libstdc++-v3...

grep -R check_effective_target_dfp testsuite | grep ".exp" | grep -v svn | grep -v Change

nothing appears.
