Can't parse function declaration with unnamed static array #539

Closed gperciva closed 4 months ago

gperciva commented 6 months ago

Thanks for this library! I'm having great fun using it to nitpick some code.

Attempting to parse a function declaration with an unnamed static array:

from pycparser.c_parser import CParser
CParser().parse('void f(int [static 10]);')

fails with:

  File "/usr/local/lib/python3.9/site-packages/pycparser/plyparser.py", line 67, in _parse_error
    raise ParseError("%s: %s" % (coord, msg))
pycparser.plyparser.ParseError: :1:13: before: static

If we name the argument -- i.e. (int x[static 10]) -- then it works fine (since the example would be exactly the same as #21, the issue which prompted support for static arrays in the first place). Omitting the argument name is valid in C99.

I'm using pycparser 2.22. Thanks again for this library!
