If there were an option (I guess this would be in cpplib) to specifically
enable //-comments, we could use "-std=c{89,90} -but-with-//-comments-too".

I think "-//" would a neat command-line switch.  :-)  Maybe -f// or ...


Something else, though:  we need to decide whether we want to use
this when building the library itself, or when running tests for system
characteristics, or both.  This thread originally started off because SCO
OpenServer presents a different set of headers in ANSI mode, so the headers
seen during configuration aren't the same headers seen during building,
or during the testsuite runs.

The // issue bit me when building the library itself.  If we only look
for strict ISO-ness during configure tests, that wouldn't be a problem
(presumably the system headers won't have // scattered around).
