Solaris 2.8 -- #undef'd ostream::operator<<(long long)

[Denis Vakatov]

Hi,

The IOSTREAM formatting I/O apparently has ceased to exist on
Solaris 2.8 (and, I guess, all other "non-C99" platforms):

gcc-3.0/libstdc++-v3/configure:

  # iostreams require strtoll, strtoull to compile. If the
  # GLIBCPP_ENABLE_C99 tests found these, and if C99 support is enabled,
  # go ahead and allow long long to be used.
  if test x"$enable_c99" = x"no"; then
    enable_long_long=no; 
  fi


I may not know the whole truth ;-), but this looks a bit of extreme to 
me to disable IOSTREAMs "long long" support, which (according to the
above CONFIGURE comment) does not actually require 100% C99 conformance...

Maybe it would be enough to just add a CONFIGURE test
for strtoll() and strtoull(), and enable IOSTREAMs "long long" support
if these two are available (they are present in Solaris 2.8).

What do you think?

Cheers,
