Hello Peter,
OK, now I understand the source of your confusion. Yes, the script
compiler/bzconfig is out-of-date with respect to the form of the
config.h file that is now used with blitz. At some point during our
migration to the use of autoconf, we decided to use the m4 macros for
testing C++ compiler features (many of which came from blitz!) and scrap
the use of the bzconfig script altogether. So the items in the compiler
area are really only there for historical reasons. One should use the
autoconf-generated configure script to produce the bzconfig.h file.
In what environment were you trying to use the beta ms compiler? If it
is within the VS.NET IDE, there is a special zip file within the blitz
directory containing support files for this purpose. See the file
README-VS.NET.txt for more information. The zip file Blitz-VS.NET.zip
also contains a file blitz/ms/bzconfig.h. So you can extract this file
by itself if you want to somehow try to use the ms compiler outside of
the VS.NET IDE. Is this what you are after?
Regards, Julian C.
