Huh? Autoconf's doc says:
-- Macro: AC_PROG_YACC
If `bison' is found, set output variable `YACC' to `bison -y'.
Otherwise, if `byacc' is found, set `YACC' to `byacc'. Otherwise
set `YACC' to `yacc'.
Really I don't see a difference between the situations for bison, gperf, and
gaa. All three are development tools needed by the maintainer but not needed
for users of a tarball. All three are not among the set of tools required
by 'configure'.
The only difference I see is the immediate reference to the download location
in the gaa macro, but this is what an INSTALL or DEPENDENCIES file is good for,
no?
