That's weird...you're not using automake?  You need to call bison with
the -p "glcpp_parser_" option.  This changes the prefix on all functions
from the generic "yy" to "glcpp_parser_" to avoid symbol conflicts.

Alternatively, I think we could specify it in the .y file via:
%name-prefix glcpp_parser_

which might be a better idea, since it works independently of the build
system.
