// Test for message: bit-field of type plain 'int' has implementation-defined signedness [344]
/* lint1-extra-flags: -p */
/*
* C90 3.5.2.1 allows 'int', 'signed int', 'unsigned int' as bit-field types.
*
* C99 6.7.2.1 significantly changed the wording of the allowable types for
* bit-fields. For example, 6.7.2.1p4 does not mention plain 'int' at all.
* The rationale for C99 6.7.2.1 mentions plain 'int' though, and it would
* have broken a lot of existing code to disallow plain 'int' as a bit-field
* type. Footnote 104 explicitly mentions plain 'int' as well and it even
* allows typedef-types for bit-fields.
