fprintf -> YYFPRINTF

[Bob Smith]

Using bison 2.3 to generate a parser which runs under Windows, I 
browsed the .C file which bison generates and noticed that I wasn't 
seeing all of the messages in the output that bison generates, e.g.

Reducing stack by rule 6 (line 122):
   $1 = nterm Stmt ()

Then I noticed that there are three places in the .C file generated by 
bison where fprintf is used (two in the body of yy_reduce_print and 
one in the #define for YY_LOCATION_PRINT).  To make it easier to 
redirect those calls, it would be helpful if those names were changed 
to YYFPRINTF or some other redefinable name.  I already redirect 
bison's other messages to my local routine via

#define YYFPRINTF       pl_yyfprintf

so, a simple workaround is to use

#define fprintf         pl_yyfprintf

but I would prefer for bison to use YYFPRINTF instead of fprintf.
