VisualStudio 2005 includes two 'bugs'. The first is not really,

it allows massively parallel compilation within a project or even
across projects.  Unfortunately step one of both the ces and ccs
iconv charset compilations is to create a precompiled header of
the iconv.h contents, and the resulting iconv.pch cannot be written
by both projects as they race to the finish.  Make the longer build
dependent upon the shorter build.

The other bug is a bug we will not fix, also related to parallel
compilation.  MS blindly attempts to make a new BuildLog.htm in
each Intermediate_Dir of the project.  Of course with parallel
compilation, this falls down; we are building two projects in the
same tree at the same time.  Chalk this up as a bug for MS to fix.
