0.6.3 is very old release. There was lot of releases since this one (0.6.4, 
0.6.5, 0.6.6, 0.7.0, 1.0.0, 1.1.0, 1.1.1, 1.2.0)

As you talk about pppoE, I thought you use the CVS head.

Take a look to :
https://savannah.nongnu.org/cvs/?group=lwip (for lwIP CVS checkout)
http://www.nongnu.org/cvs/ (for CVS generic concepts)
http://www.tortoisecvs.org/ or http://www.wincvs.org/ (for some Windows CVS 
tools)

>Also for CVS checkout you have mentioned

??? No, I give you this link for general lwIP documentation, like 
initialization steps, not for checkout

I'm not sure to understand. What unix/linux related files ?

For your information we are using lwip 0.6.3
also i could see 1.2.0 is the version available now...
but in that i couldn't see the macros u have mentioned. PPPOE_SUPPORT=0 
PPPOS_SUPPORT=1 and pppOverSerialOpen 

Correct me if i am wrong

It will be more useful if u refer how to get this source code meaning CVS 
checkout through Windows.Also for CVS checkout you have mentioned 
http://lwip.scribblewiki.com/LwIP_Main_Page  this site is having unix/linux 
related files.I am new to Linux kindly refer this for Windows.
