You can recompile this on a TIGCC system by patching the system <default.h>
include file and replacing the line:
    #define __ATTR_LIB_C__ __attribute__((__regparm__(4)))
with the lines
    #ifdef REGPARM1_STDLIB
    #define __ATTR_LIB_C__ __attribute__((__regparm__(1)))
    #define CONFIRM_REGPARM1_ENABLED
    #else
    #define __ATTR_LIB_C__ __attribute__((__regparm__(4)))
    #endif

This has been tested with TIGCC 0.94SP4. Newer versions will likely require
adaptation of this source code and/or toolchain.
