[Gc] GC version numbering

[Ivan Maidanski]

Hi Hans,

We can switch to the new policy starting from 7.3 by replacing "alpha" component to "micro" one.

For gc-7.2 (+ the fix) alternatives are:
1. don't alter anything, just do "make dist" and rename tarball to gc-7.2-201205DD or to gc-7.2.1 or gc-7.2b, or even to gc-7.2.10 (be greater than any alpha released)
2. same as above plus alter version in Readme and configure to 7.2.1 (or 7.2.10 or 7.2-201205DD)
3. same as above plus just add GC_VERSION_MICRO (set to 1 or 10) to gc_version.h.

What do you prefer (for exactly this hot fix)?

Regards.

It makes sense to switch to a version numbering scheme that handles small bug fixes like this better.  Unfortunately the obvious alternatives seem to cause the GC_version variable to behave strangely, so that "newer" no longer corresponds to ">".  Maybe we just need to introduce a revision number which isn't reflected in GC_version for now and switch to a different scheme when we would otherwise bump the version to 7.4.
