oyacc, is a portable version of the OpenBSD Yacc program.
It is suitable for ensuring standard Yacc compliance, for older Unix machines
that do not have a free Yacc or have a very old Yacc, or for users that do not
need the bells and whistles of
yacc has no dependencies other than libc. It is known to build and run on all
*BSD flavors, Linux, Mac OS X, Cygwin, AIX, and Solaris. It is very likely to
run on other Unix flavors; please let me know if you are using this on a Unix
not listed here so that I may add it to the list.
To build, run:
$ ./configure $ make # make install
Tested on Linux and Mac OS X using TravisCI. *BSD, Cygwin, AIX, and Solaris testing done manually. AIX 5.1L and Solaris 8 are used to help ensure backwards compatibility.

portable.c are 3-clause BSD licensed.
