FYI: bladeenc - fairly easy port.

["Hannu E K Nevalainen \(garbage mail\)" <garbage_collector at telia dot com>]

As I understand there might be issues WRT copyright on mp3-encoding.
There is some wording on this at the site indicated below.

Therefore I have to ask;
Will it be a "to high risk" to include bladeenc in cygwin as a package?

Below you can see that it is LGPL too; would that be a hindrance?

Now to my results...  (I'll polish/check the needed patches, before handing
them out).

This is on a P2 @450 MHz

i.e. size is approximately 9% of original files.

I have run the recommended test; compile a "CFLAGS = " version (w no
optimizations) and md5sum-tested the output to that of an "CFLAGS = -O2"
version.
This test was fine; i.e. the output files didn't differ.

Approximate speed difference:
 -O2 runs 1.75x speed
 -O0 runs 0.75x speed (P2/450!)
 -O0: "All operations completed. Total encoding time: 00:47:46"
 -O2: "All operations completed. Total encoding time: 00:20:04"
