I agree this extension is a mess and a bad idea. Besides, you can already
approximate what you want without further extensions:
#define __pascal_string(s) \
((const unsigned char *)&(struct { \
unsigned char __len; \
const char __string[__builtin_strlen(s)]; \
}){ __builtin_strlen(s), s })
(Note, however, that the result of __pascal_string here has only C99 block
scope, which may not be what you want, and that there are some bugs in the
handling of compound literals.)
