Well, I figured out my problem - cygwin gets its locale implementation
from
newlib which only sup****ts C locale
(http://sourceware.org/newlib/libc.html#SEC183).
For the OP, your problem may be similair, in which case converting the
","s to
"."s (possibly on-the-fly) should solve your problem:
$ echo 4,321 | gawk '{gsub(/,/,"."); $0 = $1 + 1; gsub(/\./,",")}1'
5,321

Ed.
