# Makefile for irix/cmd/bison
#

# Via a small amount of artifice in this Makefile we've managed to use the
# virgin bison sources with only a single small change in files.c to support
# finding bison.simple and bison.hairy relative to $ROOT.  If any non-SGI-
# specific changes are needed in the bison sources please communicate them
# immediately to the current bison maintainer so we can more easily upgrade
# to future releases.  The README file in the sources describes where to send
# bug reports.

# We use /usr/lib for SHARELIBDIR instead of /usr/share/lib because using the
# later introduces some conflict with the spec/idb nightmare that insists that
# we don't have /usr/share and non-share files coming out of the same
# subsystems.  Since the only thing we put in SHARELIBDIR are the bison.simple
# and bison.hairy templates and since bison is currently the only such problem
# child, we just toss them into /usr/lib ...

# We have to pass the datadir definition down to the bison Makefile because
# it doesn't follow the autoconfigure rules.  The datadir definition
# is used by bison to find bison.simple and bison.hairy.  All the other
# destination directory configuration is unimportant since we do the
# installations here.
