build 'make check' in tests/cxx: error in tests.h (HAVE_SSTREAM configure bug)

[anirkko at insel.ch]

Hi
gmp-4.2.1 build aborts during 'make check' in tests/cxx/
because HAVE_SSTREAM is not set in line 421 of file tests/tests.h
(see output below).
Error during configure? Header file with definition of HAVE_SSTREAM
not included?

Workaround for my system: Replace
  #if HAVE_SSTREAM
by
  #if 1
then everything works and all tests PASS.

Looking at the whole directory tree closer with grep, the only two
files which contain HAVE_SSTREAM are the above tests/tests.h
and the file config.in, which has only '#undef HAVE_SSTREAM'
However, sstream is standard nowadays according to the gcc-4.1.2 messages.

Best regards,
Arto

     a grep reveals that it doesn't contain any HAVE_SSTREAM.
     (in fact, neither has configure).
