In theory, it should be possible to build autoconf-based programs even
if you can't run configure or make.  Copy config.h.in to config.h,
manually edit system specific matters, and invoke the compiler and
linker manually.  It is sometimes easier to make autoconf/make work on
the system, though...

We discussed this some more, and we'll likely add an OpenSSL-like
version number integer.  If that works, I'll remove this symbol, since
the version number integer is more generic.  And it would be less
maintenance work for us.
