MKS sh problem (follow-up)

A follow-up from Jeff to the last MKS report.  My comments are in

MSVC Issue
The suffix on C++ source files [in groff] has been changed to '.cpp',
but in testing whether the C++ compiler works, configure gives it a
'.cc' file, which MSVC does not recognize.  Changing all instances of
ac_ext=cc to ac_ext=cpp solves the problem.

[With other words, AC_LANG and AC_LANG_PUSH (or another appropriate
autoconf macro) need a second argument to specify the extension of
test programs.  BTW, there is a documentation error: In autoconf
version 2.59, extension `.cc' is used for C++ test programs, not `.C'
as mentioned in the AC_LANG description.]

Win32 Issue
Configure correctly discovers '.exe' as the executable suffix, but
doesn't use it when searching for C and C++ compilers, so it fails to
find cl in either case.  Changing every instance of 'cl' to 'cl.exe'
effects a quick fix, but making use of the executable suffix would be
more elegant as well as more portable.  Setting the variables 'CC' and
'CXX' is another interim fix.
