62 # Some of our targets (cross-option.texi, bison.1) use "bison --help".
63 # Since we want to ship the generated file to avoid additional
64 # requirements over the user environment, we used not depend on
65 # src/bison itself, but on src/getargs.c and other files. Yet, we
66 # need "bison --help" to work to make help2man happy, so we used to
67 # include "make src/bison" in the commands. Then we may have a
68 # problem with concurrent builds, since one make might be aiming one
69 # of its jobs at compiling src/bison, and another job at generating
70 # the man page. If the latter is faster than the former, then we have
71 # two makes that concurrently try to compile src/bison. Doomed to
72 # failure.
73 #
74 # As a simple scheme to get our way out, make a stamp file,
75 # bison.help, which contains --version then --help. This file can
76 # depend on bison, which ensures its correctness. But update it
77 # *only* if needed (content changes). This way, we avoid useless
78 # compilations of cross-option.texi and bison.1. At the cost of
79 # repeated builds of bison.help.
