FD_SETSIZE is not a kernel variable, it's just used by the macro's
for handling select() fdlists. Adding a -DFD_SETSIZE=2048 (yes,
that's without the __) to the correct conf-file in the qmail source
should do the trick.
Ok, found it. This is what I do in my installscripts:
echo Fixing $QMAIL/conf-cc...
echo 'cc -O2 -DFD_SETSIZE=4096' > $QMAIL/conf-cc
