use a direct strcpy(), as it can be inlined and optimized to simple
processor operations, unlike ast_copy_string().
* String conversions
--------------------
When converting from strings to integers or floats, use the sscanf function
in preference to the atoi and atof family of functions, as sscanf detects
errors. Always check the return value of sscanf to verify that your numeric
variables successfully scanned before using them. Also, to avoid a potential
libc bug, always specify a maximum width for each format specifier, including
integers and floats. A good length for both integers and floats is 30, as
this is more than generous, even if you're using doubles or long integers.
* Use of functions
