Thanks for the bug report. Fixed as follows.
The fact that AC_PROG_CXX sets CXX to g++ as a default seems to me like
a bug in Autoconf. The code used gcc as a default up to commit
d9409a1c3c06a015a0fc829989cb1a93c1599cd7
which it had ever since AC_PROG_CXX was added 1994 in commit
8202df5faf642cde4e5b1fa02cd9cc4411a7a477
I'll propose to remove that in Autoconf.
Cheers,
Ralf

* tests/testsuite.at (LT_AT_TAG): For the CXX tag, if $CXX is
g++, check that `g++ -v' works; AC_PROG_CXX may have set that
as default value even if it found no C++ compiler.
