mercurial build error on windows

[Angel Ezquerra]

Hi,

I got a Windows 2008 server that runs an automated build of mercurial
and tortoisehg nightly. Today I saw that the thg build of the head of
the default branch (using the mercurial default branch head) failed as
follows:

hg-build\winbuild>hg summary -R build/hg
parent: 19040:12acbea17625 tip
 dispatch: print 'abort:' when a pre-command hook fails (BC)
branch: default
commit: 1 unknown (clean)
update: 29 new changesets, 11 branch heads (merge)

It seems that some of the recent patches to the C parser made by Bryan
fail to compile on windows? I checked the code briefly but I did not
see anything obviously wrong.

Cheers,
