| * and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long, |
| * 'p'=linear pointer, 't'=linear pointer to null-terminated string, |
| * 'T'=segmented pointer to null-terminated string). |
| * |
| * The generated routines fetch the arguments from the 16-bit stack (pointed |
| * to by 'args'); the offsets of the single argument values are computed |
| * according to the calling convention and the argument types. Then, the |
| * 32-bit entry point is called with these arguments. |
| * |
| * For register functions, the arguments (if present) are converted just |
