First of all - I reccommend using your linux machine to connect to the 
internet, and then just recompile your kernel to include ip 
masquerading, and enable ip masquerading. 
I use these lines in /etc/rc.d/rc.local

ipfwadm -F -v -p deny
ipfwadm -F -v -a m -S 192.168.0.0/24 -D 0.0.0.0/0

You'll prolly want to the load the various modules, etc. 
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_irc
etc.

Then just set the win95 machine to use your linux machine as a gateway 
in the tcp/ip config in the network section in the control panel.
(ie. your netcard should have something like 192.168.0.1 as its address 
- your ppp device should get a dynamic IP I assume, which will be 
seperate. Assign the netcard in the win95 machine an ip like 
192.168.0.2, with a gateway of 192.168.0.1) To test the link, try 
telnetting to your linux machine (at 192.168.0.1) from the win95 
machine, when neitehr is connected tio the intenet.

-----------------------
Alternatively, to make your linux machine use the win95 to goto the 
internet, you should really only have to change the gateway settings on 
your netcard...However, I haven't really tried this direction in 
practice, so I am just assuming that wingate works like ipfwadm for 
linux does. (To change the gateway, just fiddle with ifconfig a 
little.))
