It appears to be a GNU C extension: https://gcc.gnu.org/onlinedocs/gcc/Case-Ranges.html but I couldn't find the history of the extension. I believe it is not in standard C (not sure about clang).

Clang supports almost all GNU C extensions. Maybe not nested functions because they need executable stacks.
