Yes, I've been considering switching for some time (especially given 
the...mess...that IJG libjpeg development has been for the past few years.)

I'm willing, unless there's strong objection from the list.

BTW, which processor do we target these days in 32bit cygwin, as that 
will affect which SIMD instruction set is enabled whn libjpeg-turbo is 
built? i686?
