Dear Eli,

thanks for your help !

| Is FP the so-called ``frame pointer''?  If so, this is the EBP
| register, and in DJGPP you need to say simply this:
|
|   fp = (void *)env->__ebp;
|

Great and in which register is the PC (program counter) stored ?

pc = (void *)env->__ ?

| That's it!
|
| (A program which uses such intimate details of data structures
| internal to the library is highly non-portable, so you shouldn't be
| surprised it doesn't work on anything but GNU/Linux.  In fact, I won't
| be surprised if it will break on some future Linux system as well.)

I see ;).
