Let me show the diff I made based on a couple weeks ago:

Note some things that the repo-owner would need to do:

1.  The AC_DEFINE for VERSION_REVISION is based on the repo's date, in
    YYYYMMDD format, of 'this cut' of the branch.  I like to put an
    "official" date on/in the code (not just "when compiled" etc.).  ;)

2.  Most Important:  The GIT_REV string should be changed for your actual
    hosting / userid / path etc., so people would know how to find it.
    If there's a way for git to tell this automatically, I'm all ears.  ;)

3.  I inserted the hostcc= line to get the current compiler's version
    string.  I'll have more on this a bit later below.


For the compiler-user:

4.  A thing I don't know quite how to do automatically is to get the
    runmode (32-bit or 64-bit).  This gets substituted into the next
    line for PLATFORM_INFO.  I seem to always step-into these kinds of
    quandrys; maybe someone knows how this could be automatically
    computed?.


Additional info for the hostcc compiler string (#3):

Sometimes a vendor puts out a hellaciously-long string for their compilers.
Once the config.h file is generated, I'll manually edit it to shorten the
#define for PLATFORM_INFO to condense its info quite a bit.  I'm not sure
how to do this automatically, even knowing about awk & sed etc., since
versions-strings (esp'ly non-GCC) can be quite various and not work thru
general filters.  ;)

But this patch can be used for starters.  ;)
