sorry for replying late, I was missed this problem somehow in my bugzilla
folder. The test in question verify that variables that are common or weak are
also either public or external.
No doubt about that.
The following piece of code, will not build with gcc 3.4.3 or gcc 4.4.1 on the
above SPARC system. It does build on at least some Linux systems. It is
somewhat similar to bug #21057 though that was reported against the C++
compiler g++, rather than gcc.
It will not build on an Open Solaris

the ABI is a likely
cause because, as you say, the C++ ABI

Please update your compiler to at least the latest
4.2.x release. A better choice would be a vesion
from the 4.4 releases. In fact, you can get pre-compiled
version of gfortran from the gfortran wiki.
The 4.0.1

For me, the testcase doesn't abort or exit successfully,
it just segfaults (i686, x86_64, gcc-4.3, 4.4).

The test case added with this PR appears to be rather broken. On armv5tel with
gcc-4.3 or 4.4 (without the fix) -Os -mthumb I do get an abort(), which seems
deliberate. However, replacing -Os -mthumb with -O0 -g results

Sorry. The following change would fix it on X86.

I have reverted the whole patch on mainline and 4.4
That was unnecessary.
I will modify the testcase and send the whole patch again.
Just send a message to gcc-patches@ and apply the fix to the testcase.

FYI, if you always want to test a NaN, you'd need to use big endian ordering
for some arches, plus there are targets which don't support NaN at all or where
a double isn't as big as 4 shorts.

What we want to do is to run the libstdc++ testsuite with my
distribution-provided g++, in order to see whether it's generally broken or
not, right?

Hey, I'm telling you the way we all library maintainers (like me) and users
check the library: they all fetch everything (either mainline or 4_4-branch, or
whatever) via svn, make, make check. Now you want to
