New submission from Dave Malcolm <dmalc...@redhat.com>: With hg/mercurial 0.9.3, the build of CPython fails with this error:

This means that the post-processed code isn't valid C. The workaround presumably is to upgrade to a more recent version of mercurial. I'm reporting this here in the bug tracker in case anyone else runs into this problem. [1] Adding "-v" to the gcc invocation demonstrates that the values being passed are: -DHGVERSION="hg identify print information about the working copy Print a short summary of the current state of the repo. This summary identifies the repository state using one or two parent hash identifiers, followed by a "+" if there are uncommitted changes in the working directory, followed by a list of tags for this revision. aliases: id" -DHGTAG="hg identify print information about the working copy Print a short summary of the current state of the repo.
