[boost] [fusion] fusion::map broken for Visual Studio 2005?

From: Michael Marcin (mmarcin_at_[hidden])
Date: 2006-12-21 18:03:08

Attached is a simple repro (taken directly from the fusion::map 
documentation example).

It fails to compile on Visual Studio 2005 using CVS HEAD from today the 
message below.

Fusion::map solves a current problem I have rather elegantly but this is an 
obvious showstopper.

Any ideas?

Thanks,

Michael Marcin
