In all files, all occurrences of "[eva] done for function" have been replaced
by "[eva] Done for function".

There are still many missing specifications, but at least parsing should
succeed for strictly POSIX-compliant code.

Frama-C does not yet support _Alignof and _Alignas, but this header helps
parsing code and emitting a proper error message.

Clang 13 emits warnings related to uninitialized variables:

variable 'r' is used uninitialized whenever 'if'
condition is false [-Wsometimes-uninitialized]

This is due to the fact that the assert(0) macro, when using Frama-C's libc,
is expanded to __FC_assert. Since it is not known by the compiler, it cannot
consider it as "noreturn" when the condition is zero. Note that adding
'__attribute__ ((__noreturn__))' will not work: Frama-C will assume it
never returns, even when the condition is true.
Initializing the 'r' variables with a default value will not change the
actual behavior, and will avoid the warnings.

Due to the absence of a long double version of the pow() logic function,
and due to likely little demand for ldexpl, this function has not been
specified.
