Some quotes from the standard: "The purpose of [POSIX] is to define a standard operating system interface ... to support application portability at the source level." (POSIX.1, pg ix, lines 1-3). "Source, Not Object, Portability This part of [POSIX] has been written so that a program written and translated for execution on one conforming implementation may also be translated for execution on another conforming implementation. This part of [POSIX] does not guarantee that executable (object or binary) code will execute under a different conforming implementation than that for which it was translated, even if the underlying hardware is identical." (POSIX.1, page xii, lines 115-122) If someone paid "money" for the advice that POSIX is "binary compatable", he should get his money back from a consultant who obviously hasn't read the POSIX.1 standard. dave emery
