Also, in appendix J.5.10 the C99 spec does at least formally mention
the issue of inline assembly.  It even gives an example of a common
statement syntax.  It's not part of the language definition, though;
appendix J.5 is an informational list of common language extensions
such as inline FORTRAN, extra-large numeric types, and being able to
convert a function pointer to an object pointer and then access the
function's code.

...or dread the thought of having to write or worse yet debug assembly
by hand because the architecture makes it so difficult (obvious
example is Itanium2).
