problem with pasting two tokens together in gcc 3.4

[Deepak Soi <sdeepak@xxxxxxxxxxx>]

Hi,       
      Yes, you are right problem we are facing is with pasting two 
tokens together, but what I am unable to understand is why its compiling 
properly with older gcc versions. Is there any change in gcc3.4 handling 
of macros.I will be thankful for your help on this.

======================================================================
Error

find.cxx:723:1: pasting "DbNet" and "*" does not give a valid 
preprocessing token.

 find.cxx:723:1: pasting "Net" and "*" does not give a valid
preprocessing token.
 find.cxx:723:1: pasting "FindFromDbNet" and "(" does not give a
valid preprocessing token.

=====================================================================

regards
Deepak Soi
