[tlbuild] Testing cxx-runtime-hack -- V 1.1

[Karl Berry]

Hi Thomas,

    iostram.h is, according to this page http://www.gnu.org/software/gcc/gcc-4.3/porting_to.html 
      , a deprecated header; 

I doubt the new replacements are supported in the old compilers/system
we work on.  And plenty of our existing code uses iostream.h.  We can't
rationally change any of that.

Is it a matter of specifying other compiler flags, or that some
compatibility package needs to be installed on your system, or it's
simply and completely not available?  (Which I rather doubt, or no
compilation of TL would ever have succeeded for you.)
