* Modified heavily since then.
*
* Synopsis:
* unexec (new_name, a_name, data_start, bss_start, entry_address)
* char *new_name, *a_name;
* unexec (new_name, old_name, data_start, bss_start, entry_address)
* char *new_name, *old_name;
* unsigned data_start, bss_start, entry_address;
*
* Takes a snapshot of the program and makes an a.out format file in the
* file named by the string argument new_name.
* If a_name is non-NULL, the symbol table will be taken from the given file.
* On some machines, an existing a_name file is required.
* If old_name is non-NULL, the symbol table will be taken from the given file.
* On some machines, an existing old_name file is required.
*
* The boundaries within the a.out file may be adjusted with the data_start
* and bss_start arguments. Either or both may be given as 0 for defaults.
