"Use" in the sense of distributing applications linked against it,
yes.
In this case I don't think it's a problem. The output of 'flex' and
'bison' is not required to be GPL (there is a specific exception in
the Bison license for this), and we're not distributing any Cygwin
code, or any binaries linked with it, merely using it to generate
parts of the PG source tree.
