dnl CXXFLAGS - C++ flags to use during the configure script run and
dnl during ACE compilation. The user may set this prior to
dnl running the configure script. As such, it is important
dnl not to replace the existing value of CXXFLAGS; rather
dnl one should only add to it.
dnl ACE_CXXFLAGS
dnl - General C++ flags the configure script should set before
dnl CXXFLAGS to allow the user override them.
dnl DCXXFLAGS - C++ debugging flags
dnl OCXXFLAGS - C++ optimization flags
dnl CPPFLAGS - C++ preprocessor flags
dnl ACE_CPPFLAGS

dnl script should set before CPPFLAGS to allow the
dnl user override them.

dnl IBM C/C++ compiler 3.6.x produces a bazillion warnings about
dnl 0-valued preprocessor defs. Since both 3.1 and 3.4 could
dnl be installed, don't ask lslpp for one or the
dnl other. Instead, compile a file and see which compiler the
dnl user has set up for use. This trick was submitted by
dnl Craig Rodrigues <rodrigc@mediaone.net>, originally from
dnl the vacpp compiler newsgroup. It relies on the
dnl preprocessor defining __xlC__ to the proper version
dnl number of the compiler.
