Also stop redefining system `basename()` symbol. Call `curlx_basename()` instead, and map that to `basename()` if available. Closes #20424

(Quote from The Open Group Base Specifications Issue 6 IEEE Std 1003.1, 2004
|
|
Edition)
|
|
|
|
The basename() function shall take the pathname pointed to by path and
|
|
return a pointer to the final component of the pathname, deleting any
|
|
trailing '/' characters.
|
|
|
|
If the string pointed to by path consists entirely of the '/' character,
|
|
basename() shall return a pointer to the string "/". If the string pointed
|
|
to by path is exactly "//", it is implementation-defined whether '/' or "//"
|
|
is returned.
|
|
|
|
If path is a null pointer or points to an empty string, basename() shall
|
|
return a pointer to the string ".".
|
|
|
|
The basename() function may modify the string pointed to by path, and may
|
|
return a pointer to static storage that may then be overwritten by a
|
|
subsequent call to basename().
|
|
|
|
The basename() function need not be reentrant. A function that is not
|
|
required to be reentrant is not required to be thread-safe.
