What's new/corrected in the new beta (and the previous)?

Mostly fixes to help boost compile.

I have tested the new beta against some code from the lambda library.

Here is an example which does not compile, extracted from this code,
together with output from the compiler.

Here's another more complicated example from the same source.  I had to
copy quite a lot of code to be sure that everything is defined, but the
error is a oneliner at the very end.

template <class HT, class TT> struct cons -- is not defined.

That does not mean that something wasn't causing a problem, just that your
example needs a little more work. What were you doing that generated your
original error?

Sorry for delay - away sick over the weekend.  Yes, cons is another of the
macros. It may be in the other file I uploaded.  I will check it out - and
also run the examples on the next beta.

I was running the complete file and had exactly the same error as I reported.

Adding the definition of cons does not change the error message at all.

The material comes from an old version of the lambda library before it was
added to the boost libraries.  The error message is reported by the complete
file.

Since it is older sources, I'm guessing it was a little buggy. Most folks expect
to see:

inline void fn() { }

as oppossed to:

void inline fn() { }

Richard

I am not clear whether the position of the inline at the start of the statement
is
compulsory or conventional.  As it compiled with another compiler in cannot be
said
to be a bug in the source code, so much as a compiler dependence issue, unless
the
other compiler went beyond the standard.

The code concerned (lambda library) is one which I started to use in my
programs and
it has prevented me using those versions with DM because the compiler didn't
compile
it.  That is quite a separate issue from the subsequent migration of that code
into
the Boost library in a different form.

It isn't my code so I didn't decide where to put the keywords.  I  have been
attempting to help improve DM by isolating the reasons why code which worked
e.g.
with gcc 2.95.n didn't work with DM.  Between us we have just found out one
reason,
and know a work around, for which thanks.

I hope sometime soon the whole of Boost will work with DM, but I know that is a
difficult target as Boost keeps growing.

I am grateful for the work you, Richard, and Christof have done to isolate
problems and thereby improve the compiler.

We're not there 100% yet, but there have been big improvements.
