[ns] a probelm when compiling

[Gautam - Chakrabarti]

yeah its me I guess who gave the earlier "solution". I found this
problem with gcc is kinda famous among users trying to install those
versions, i havent solved it myself, but u can try searching google with
something like "gcc installation problem" or "gcc streampos" or .... ,
actually it seemed to me earlier streampos was defined as "long long",
which they have changed later, so half of ur gcc is old, half is new.
Btw, I got this from google, searching it gives a patch that u can
install for gcc....

best wishes,
gautam
