[GCC-XML] VC mode?

[Drumheller, Michael]

GCCXML folks:

I recently sent "Message 2" (below) to c++-sig at python.org and received
the suggestion in "Message 3" from Dave Abrahams below that I ask the
GCCXML community about VC compatibility mode.  

Basically, I seem to be in VC compatibility mode but do know why, or how
to undo it.
Can anyone help?

Thank you very much.

To: <c++-sig at python.org>

I am having trouble running Pyste version 0.9.30 (gccxml version 0.6.0)
with Boost MPL 1.32 on Windows XP.  A complete (and trivial) example
that demonstrates the problem is included below

The problem has to do with the #ifdef's based on _MSC_VER that appear in
files such as or.hpp, and.hpp, etc.  It seems that _MSC_VER *is*
defined, but does anyone know why that should be?  After all, it is
GCCXML that is being run, not the VC7 compiler.   I found this page
which is probably address similar problems, but has no fixes that I can
discern.
<<http://mail.python.org/pipermail/c++-sig/2005-August.txt>>

Note:  This actually came up because I was trying to run Pyste on a file
that contained classes that use Boost.Serialization to serialize
themselvs, and Boost.Serialization uses MPL a lot.  I noticed that the
first signs of problems stem from the MPL headers, as in my example
below, and I am _hoping_ that once I fix this Boost.Serialization will
just work.
Has anyone else had success running Pyste on Boost.Serialize'd classes?

Thank you.

Class("MplTest",  "MplTest.h")

I don't think that's related.  GCC_XML seems to be running in a VC
compatibility mode.  This seems to be a GCC_XML problem; I suggest you
ask on its mailing list.
