At the cost of annoyingly repeating myself, patches touching the linker script,
and versioning, etc, *must* be always tested on Linux too. Thanks.

I got

/export/gnu/import/svn/gcc-test/src-trunk/libstdc++-v3/testsuite/../scripts/extract_symvers:
line 88: nawk: command not found^M

or

/export/gnu/import/git/gcc/libstdc++-v3/testsuite/../scripts/extract_symvers:
line 55: [: pvs: binary operator expected^M

Linux has pvs:

[hjl@gnu-1 testsuite]$ rpm -qf /sbin/pvs
lvm2-2.02.73-2.fc13.x86_64
[hjl@gnu-1 testsuite]$ 

# Sun ld doesn't record symbol versions in .dynsym entries and they cannot
# easily be extracted from readelf --versions output, so use pvs instead.
if type pvs 2>&1 | grep 'not found' > /dev/null; then
    :
else
    pvs="pvs -dsvo"
fi

is completely bogus.

Also

if [ -n ${pvs} ]; then
    ${pvs} ${lib} | \

needs a quote like

if [ -n "${pvs}" ]; then
    ${pvs} ${lib} | \
