Hi,

Following up on my last note about build problems on x86_64, I've 
committed the following patch which should fix all the compiler warnings 
about type conversions and pointer size assumptions.

ChangeLog
2008-03-07  Keith Seitz  <kseitz@sourceware.org>

         * generic/gdbtk-register.c (map_arg): New data type
         for passing arguments to mapping functions.
         (map_func): New definition of mapping function.
         Changed all callers to use these new types.
         * generic/gdbtk-stack.c (gdb_get_vars_command): Change
         cast to int to dereference of int *.
         * generic/gdbtk-wrapper.c: Change all casts to char * for
         results and args to use pointer or integer flavor of
         gdb_wrapper_args.results and .args.
         * generic/gdbtk-wrapper.h: struct gdb_wrapper_arguments
         members result and args now return a union of void * and int.
