Some Linux distributions have complained about Perl as a prerequisite
for isohybrid, so create a C version.

[ hpa: modified the array generator to put it all in one script ]

Loop over multiple files, use argv[0] for the program name, and copy

login_handler have to follow the (t_menusystem * ms, t_menuitem * mi)
prototype defined by t_handler_return

const char * confuse the *argv++ assignation
Casting to char * removes this warning

print_history have to follow the exec prototype

argv isn't a number ;)

get_error prototype changed since this module was written
