[gnutls-dev] gnutls 1.5.1 C++ library not built if CXX=g++ is set

[Andreas Metzler]

Hello,
setting CXX=g++ breaks the building of the C++ library.

(SID)ametzler at argenau:/tmp/gnutls-1.5.1$ ./configure 2>&1 |\
        grep 'checking whether to build C++ library'
checking whether to build C++ library... yes

(SID)ametzler at argenau:/tmp/gnutls-1.5.1$ CXX=g++ ./configure 2>&1 |\
        grep 'checking whether to build C++ library'
checking whether to build C++ library... no

Afaict this change to configure.in should fix it

-if test -z "$ac_cv_prog_ac_ct_CXX"; then
+if test -z "$CXX"; then

BTW, shouldn't the C++ library use symbol versioning, too?
thanks, cu andreas
