What does the C standard say about portability?

Hello,

See here:

www.open-std.org/.../C99RationaleV5.10.pdf

Is it possible that "Jack Sprat", the staunch defender of the C standard as the ultimate reference when writing programs, missed the following statement?

C code can be non-portable.  Although it strove to give programmers the opportunity to write
truly portable programs, the C89 Committee did not want to force programmers into writing
portably, to preclude the use of C as a “high-level assembler”:  the ability to write machine-
35  specific code is one of the strengths of C.  It is this principle which largely motivates drawing the
distinction between strictly conforming program and conforming program (§4).

this is precisely what Per Westermark has been saying.
Exactly what Erik Malund has been saying.
Remember: Jack Sprat claims often that writing a program that complies with the C standard is a GUARANTEE for its correct functioning.

    in my case, it is primarily to reduce labor cost and reduce time to market, by providing high quality code that has been debugged before.

    it is, from that point of view, a preservation / institutionalization of our prior investment in debugging.
