It's a prank of bison. Bison generate following code.

  #ifndef __cplusplus
  #ifndef __STDC__
  #define const
  #endif
  #endif

`SEXP mkString(const char *s)' is replaced to
`SEXP mkString(char *s)' by preprocessor.
And, cc compiler is too strict to ignore the difference
bettween type `char *' and `const char *' defined in Rinternals.h.

My configure option is here:

  CC=cc CFLAGS='-O5 -I/usr/local/include -std' CPPFLAGS='-O5 -I/usr/local/include' FFLAGS='-O5' ./configure --with-f77 --with-readline

`-std' option defines __STDC__, and then compile will be successful.
