/*
* PuTTY version numbering

/*
* The difficult part of deciding what goes in these version strings

Show the git commit hash in local dev builds too. This is perhaps the more useful end of the mechanism I added in the previous commit: now, when a developer runs a configure+make build from a git checkout (rather than from a bob-built source tarball), the Makefile will automatically run 'git rev-parse HEAD' and embed the result in the binaries. So now when I want to deploy my own bleeding-edge code for day-to-day use on my own machine, I can easily check whether I've done it right (e.g. did I install to the right prefix?), and also easily check whether any given PuTTY or pterm has been restarted since I rolled out a new version. In order to arrange this (and in particular to force version.o to be rebuilt when _any_ source file changes), I've had to reintroduce some of the slightly painful Makefile nastiness that I removed in 4d8782e74 when I retired the 'manifest' system, namely having version.o depend on a file empty.h, which in turn is trivially rebuilt by a custom make rule whose dependencies include $(allsources). That's a bit unfortunate, but I think acceptable: the main horribleness of the manifest system was not that part, but the actual _manifests_, which were there to arrange that if you modified the sources in a distribution tarball the binaries would automatically switch to reporting themselves as local builds rather than the version baked into the tarball. I haven't reintroduced that part of the system: if you check out a given git commit, modify the checked-out sources, and build the result, the Makefile won't make any inconvenient attempts to detect that, and the resulting build will still announce itself as the git commit you started from.
