How is the compiler broken, question mark.
Are you perhaps objecting to the type of the last parameter
("int format" vs "char format")? Please see Ansi Classic, chapter
"3.5.4.3 Function declarators (including prototypes)", in particular
page 69 lines 19-22. In C99, 6.7.5.3 paragraph #11 seems to apply
similarly.
If you
- define "__P" suitably
- add "struct printer;" to file scope
- add "}" to complete the function definition
to me, the above code fragment seems to constitute a valid
ANSI C89 translation unit.
