Compile of ext\ripper\ripper.c fails during 1.9 [bccwin] build

Hi,

ripper.c in 1.9.0 (2005/06/28) gives the following errors from a bcc 5.5 compile:

--------------------------
Error E2342 ripper.y 4396: Type mismatch in parameter 'msg' (wanted 'const signed char *', got 'undefined') in function
parser_yyerror
[...]
Error E2342 ripper.y 8833: Type mismatch in parameter 's' (wanted 'const signed char *', got 'undefined') in function ripper_intern
Error E2356 ripper.y 8854: Type mismatch in redeclaration of 'ripper_compile_error'
Error E2344 ripper.y 406: Earlier declaration of 'ripper_compile_error'
Error E2342 ripper.y 8868: Type mismatch in parameter 'fmt' (wanted 'const signed char *', got 'undefined') in function ripper_warn0
Error E2342 ripper.y 8877: Type mismatch in parameter 'fmt' (wanted 'const signed char *', got 'undefined') in function ripper_warnI

--------------------------

HAVE_STDARG_PROTOTYPES is defined.

bison 1.28 is from http://unxutils.sourceforge.net/

  /* This file comes from bison-1.28.  */  )


To build Ruby, I bypassed ripper because I hadn't time to debug it
but I wonder if it's related to this macro:

 #define parser ((struct parser_params*)parser_v)

... and its effect on a function declaration containing an argument with the name "parser":

   static void ripper_compile_error(struct parser_params *parser, const char *fmt, ...)

I would expect the preprocessor to expand it to this horrible mess:

   static void ripper_compile_error(struct parser_params *((struct parser_params*)parser_v), const char *fmt, ...)

... which is a redeclaration (doesn't match the prototype) and a "type mismatch".

The ripper_warn___()  functions also have "parser" in their argument names.

Some of the other errors may be caused as a result.

If needed, e-mail tar.gz compiler tests to daz[@]d10[.]karoo[.]co[.]uk .
I hope this is helpful to Aoki-san.
