Description:
------------
because of the type of various numeric values in the source code php5+x86_64 is not recognizing values passed in (seeing them as 0 when they are not)

bi_base_convert(): wrong [base_from]. It can be from 2 to 36 inclusive

bi_from_str(): length of the string must be greater than 0

bi_to_str(): argument number [1] cannot be empty 

etc...

Reproduce code:
---------------
var_dump( bi_from_str("abcd", 16) );

var_dump( bi_base_convert("abcd", 16, 10) );



Expected result:
----------------
no errors, non-null return values

Actual result:
--------------
errors, null return values

Attached a new patch for this bug that is well tested in production. Is there any 
chance we could get this committed?
