New submission from Dave Malcolm <dmalc...@redhat.com>:
With hg/mercurial 0.9.3, the build of CPython fails with this error:
gcc -pthread -c -fno-strict-aliasing -g -O0 -Wall -Wstrict-prototypes -I.

What's happening is that "hg id" doesn't recognize the given options, and thus
the various HG macros get set to insane multi-line strings containing usage
information, but without quote characters, rather than to empty string literals
[1]. 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.
