We do not support some extensions to ISO C

stdio locking functions namely flockfile(), ftrylockfile() and funlockfile() 
are not supported because "These functions can be used by a thread to delineate 
a sequence of I/O statements that are executed as a unit.".

By extension we also don't support stdio with explicit client locking which 
implies no support for getc_unlocked(), getchar_unlocked(), putc_unlocked(), 
and putchar_unlocked().

We don't support all print formatted output namely dprintf(), fprintf(), 
printf(), snprintf(), and sprintf(), as well as any functions that convert 
formatted input like fscanf(), scanf(), and sscanf().

We don't support fseeko()/ftello(), use fseek()/ftell() instead (eg. the off_t 
typedef is not that important).

getline() and getdelim() are not supported; it is easy in AS3 to to find 
delimiter or newline char in a string so we don't need native functions for 
that. At best, we could implement in AS3 those function reusing getc()/fgetc().

We don't support command option parsing namely getopt(), optarg, opterr, 
optind, and optopt because our AS3 programs do not have to follow the rules of 
main(int argc, char *argv[ ]), you can access command line arguments as an 
Array and do your own parsing.

renameat() is not supported, use rename() as equivalent function.

setbuf() is not supported, use setvbuf() instead as it got more options.

tempnam() is not supported, use tmpnam() or tmpfile() instead.
