3e08a88389 Only the (rising) overlap part of the window is stored now. No need to hold the 
zeros and ones (nor even the second half).

81b38c2295 Moved mdct state and window to the mode so it can be shared between multiple 
encoders and decoders.

a85657bd29 removed // comments and added stack_alloc.h (not used everywhere yet) 
to make the code more C89-friendly.

4c6bc884c8 "make check" now actually tried to encode and decode to see if things work 
(need to have test files installed otherwise it'll just pass by default)

f51ca493fb Looks like the bit allocation code is mostly working. Just need to actually 
use it now.

4a897680e3 Working on some stability issues (appears to be solved by making the pitch 
projection less aggressive). Also, fixed a 64-bit overflow in the stereo mode
and added a "band rotation" function.

pulses)
