That part of the code tries to read some (partly) user-generated 
input: the -A functions. If you invoke flac -A tukey(0.5) -A 
gauss(0.2) -A flattop the content of the variable specification 
central to that part of the code will be 
tukey(0.5);gauss(0.2);flattop

The partial_tukey and punchout_tukey functions have a varying 
number of parameters. The first is an integer stating a number 
of functions, the second (p) is a fraction between 0 and 1 
describing the tukey function, and the overlap is a fraction 
between -inf and 1 describing the overlap of the functions, 
where negative overlaps mean that there are gaps between the 
functions.

So, the problem here is that there is some input, read with 
strtod, but cast to an integer. It isn't something critical 
(technically, entering a non-integer number there would be 
invalid) so it is probably best to ignore it I suppose.
