Re: C2026 error in VC++ with large number of tokens

Hi,

Thank you for your reply. See the input file, ApReadBinary.ypp (I have 
reduced it greatly from the original).  The HPP file has the bad line at 
line # 3900 - the YY_ASSERT is too long.

The key parameters in the YPP file seem to be:

%language "c++"
%define parse.assert

Thank you very much for your help!
