Is it possible compile Pg 7.1.3 to run under Win98?

    I read in Postgres 7.1 docs it work only under WinNT/2000 whereas Postgres
7.2 is capable to run under Win98/ME. I wish know if it's a feature of Pg
7.2 or if it's the last version of Cygwin that allow this. In other word
compiling Pg 7.1.3 with last Cygwin can it run under Win98?

Thanks in advance
