Yet, we # need "bison --help" to work to make help2man happy, so we used to # include "make src/bison" in the commands. Then we may have a # problem with concurrent builds, since one make might be aiming one # of its jobs at compiling src/bison, and another job at generating # the man page. If the latter is faster than the former, then we have # two makes that concurrently try to compile src/bison. Doomed to # failure. # # As a simple scheme to get our way out, make a stamp file, # bison.help, which contains --version then --help. This file can # depend on bison, which ensures its correctness. But update it # *only* if needed (content changes). This way, we avoid useless # compilations of cross-option.texi and bison.1. At the cost of # repeated builds of bison.help.
