The Heirloom Development Tools package provides yacc, lex, m4, make,
|
|
and SCCS as portable derivatives of the utilities released by Sun
|
|
as part of OpenSolaris. The OpenSolaris utilities were in turn
|
|
derived from the original Unix versions, and are assumed be conforming
|
|
implementations of the POSIX standard.
