Oh? I thought it'd fail only on Windows, so I have not submitted
https://github.com/dscho/git/commit/fix-hdr-check yet:

Subject: [PATCH] hdr-check: make it work on Windows

On Windows, we define a specific set of pre-processor macros, among
other reasons: to avoid including syslog.h (which is not available on
Windows).

The hdr-check target did not use those definitions, resulting in a
failure to include said syslog.h.

To fix that, let's let the hdr-check target make use of ALL_CFLAGS,
which does include the pre-processor macros that would e.g. skip the
conditional block including syslog.h.
