problem with "#define printf libintl_printf" in "libintl.h"

[Henry Nelson]

When I compile programs that will link to both libintl and libslang,
warnings occur like:
/usr/local/include/slang.h:899: warning: `libintl_printf' is an unrecognized 
format function type

If I also try to link with libiconv, then a fatal error will occur.

Would it be possible to not redefine printf in "libintl.h"?

Thank you for any help with this problem.

PS.  The lines in slang.h which lead to warnings/errors are:
899
SL_EXTERN void SLang_verror (int, char *, ...) SLATTRIBUTE_PRINTF(2,3);
995
SL_EXTERN void SLang_vmessage (char *, ...) SLATTRIBUTE_PRINTF(1,2);
1002
SL_EXTERN void SLang_exit_error (char *, ...) SLATTRIBUTE_((format (printf, 1, 2
), noreturn));
1686
SL_EXTERN void SLsmg_printf (char *, ...) SLATTRIBUTE_PRINTF(1,2);
