The compiler complains about a const pointer being free'd and memcpy'd
to:

cairo-pdf-surface.c: In function ‘_cairo_pdf_surface_add_source_surface’:
cairo-pdf-surface.c:1208: warning: passing argument 1 of ‘__builtin___memcpy_chk’ discards qualifiers from pointer target type
cairo-pdf-surface.c:1208: warning: passing argument 1 of ‘__inline_memcpy_chk’ discards qualifiers from pointer target type
cairo-pdf-surface.c: In function ‘_cairo_pdf_source_surface_entry_pluck’:
cairo-pdf-surface.c:1666: warning: passing argument 1 of ‘free’ discards qualifiers from pointer target type
