We've opted to keep only the highest-level sources in the repository. This
eases our maintenance burden, (fewer merges etc.), but imposes more

Bison is written using Bison grammars, so there are bootstrapping
issues. The bootstrap script attempts to discover when the C code
generated from the grammars is out of date, and to bootstrap with an
out-of-date version of the C code, but the process is not foolproof.
Also, you may run into similar problems yourself if you modify Bison.

Only building the initial full source tree will be a bit painful.
Later, after synchronizing from the repository a plain 'make' should
be sufficient. Note, however, that when gnulib is updated, running
'./bootstrap' again might be needed.
