Hi Karl,

a related issue:

right now, in cxx-test-1.1.1, I have more or less copied your test and
wrapped it into an M4 macro.  Do we really need to run the test program
(analogous to AC_RUN_IFELSE) thereby causing cross-compilation problems? 
Wouldn't it suffice to just link (AC_LINK_IFELSE)?

And a related question:

How are the win32 binaries built? with 'gcc -mno-cygwin' or with a MS
compiler? DO they use the cxx-runtime-hack?
