Hi Phillip,

: Here's a patch for the bug mentioned in
: < http://gcc.gnu.org/ml/gcc-bugs/2000-04/msg00044.html >.  It seems to fix 
: the problem for me.

Well the case for '*' is fine, but I am worried about the case for
'@'.  Did you find a situation where it was needed ?  The reason I ask
is beause the arm-pe port uses the '@' to prefix to encode imported
and exported DLL symbols, and your code will clash with this.

>From gcc/config/arm/pe.h:

  #define ARM_PE_FLAG_CHAR '@'

  /* Ensure that @x. will be stripped from the function name.  */
  #define SUBTARGET_NAME_ENCODING_LENGTHS  \
    case ARM_PE_FLAG_CHAR: return 3;
