type cast parsing error in (__typeof(h))spa_meta_first(m) line, __typeof(h) type is not allowed by parser rules

Hello, while trying to run project https://gitlab.com/matpi/pipewire-py

I get an error

State  : 484
Stack  : declaration_specifiers id_declarator declaration_list_opt brace_open unary_expression assignment_operator LPAREN expression RPAREN . LexToken(ID,'spa_meta_first',3,138)

Here is the test python code with extracted code sample leading to the error

import pycparserext.ext_c_parser
import pycparserext.ext_c_generator

PREPROCESSED_SOURCE = """
static inline int spa_debugc_buffer(struct spa_debug_context *ctx, int indent, const struct spa_buffer *buffer) {
    (h) = (__typeof(h))spa_meta_first(m);

    for ((h) = (__typeof(h))spa_meta_first(m);  spa_meta_check(h, m);   (h)++) {

    }

    return 0;
}
"""

parser = pycparserext.ext_c_parser.GnuCParser(yacc_debug=True)
parser.parse(PREPROCESSED_SOURCE, debuglevel=True)

The error happens at (h) = (__typeof(h))spa_meta_first(m); because of __typeof(h) type casting which seems not considered as a valid cast type for a parser, but initial code source uses this construct and compiles fine. This is a pcpp.Preprocessor preprocessed code from https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/spa/include/spa/buffer/meta.h?ref_type=heads#L90

Is this a parser bug?
