    C23: Fix ICE for composite type for structs with unsigned bitfields
[PR113492]

    This patch fixes a bug when forming a composite type from structs that
    contain an unsigned bitfield declared with int while using
-funsigned-bitfields.
    In such structs the unsigned integer type was not compatible to the
    regular unsigned integer type used elsewhere in the C FE.

    gcc/c:
            * c-decl.cc (grokdeclarator): Use c_common_unsigned_type instea=
d of
            unsigned_type_for to create the unsigned type for bitfields
declared
            with int when using -funsigned-bitfields.
