    : hplip-sclpml-strcasestr.patch
    
    Kludge to support building C99 mode.  This should no longer be needed
    once glibc declares strcasestr by default, and not just with
    -D_GNU_SOURCE.

    : hplip-pcardext-disable.patch
    
    The pcardext Python extension cannot be loaded because it has not been
    ported to Python 3:
    
    >>> import pcardext
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ImportError: /usr/lib64/python3.11/site-packages/pcardext.so: undefined symbol: PyString_AsStringAndSize
    >>>
    
    Stop building this extension because it breaks the build if the
    compiler lacks support for implicit function declarations.

    scan/sane/orblite: Include <dflcn.h> for function prototypes
    
    This is required for C99 compatibility.  Also delete the unused
    bb_unload function because it calls a call to the undefined
    _DBG function/macro.
