Subject: POSIX , Ada, Line Feeds, etc (was Automated conversion to C+
+)

Much bogosity on this topic lately.  Several early Ada compilers,
most
notably Verdix, were implemented on Unix as well-behaved Unix
applications, and of course GNAT is available for Linux.  So any
assertion that POSIX and Ada are incompatible as a development
environment is contradicted by example.

With respect to line feeds, the Ada standard doesn't explain the
interpretation of the line feed characters on POSIX, but the POSIX
Ada
Binding (ISO 14519:2001, originally IEEE 1003.5-1992 most certainly
does.  This is very clearly documented in Clause 8, "Language-
Specific
Services for Ada".  Clause 8.1, entitled "Interoperable Ada I/O
Services" provides a specification of the Text_IO Form parameter to
handle this situation.

As one of the most widely used secondary standards, it's
disappointing
to see how few readers on this list lately are aware of the POSIX/Ada
standard and its success in supporting portable Ada applications
across
conforming POSIX (and Ada compiler) implementations.
