45 * Turns out we cannot use 'ds' for segment stuff here because the compiler
46 * seems to insists on loading the DGROUP segment into 'ds' before calling
47 * stuff when using -ecc. Using 'es' instead as this seems to work fine.
48 *
49 * Note! The #undef that preceds the #pragma aux statements is for undoing
50 * the mangling, because the symbol in #pragma aux [symbol] statements
51 * doesn't get subjected to preprocessing. This is also why we include
52 * the watcom header at both the top and the bottom of asm-amd64-x86.h file.
