Newbie question

Hi, I can see you pretty busy here, so I'll be brief: I'm trying toget inside the PHP source, but I'm not an expert in C. The flex.skl file states: #define YY_INPUT(buf,result,max_size) \ %% fread()/read() definition of YY_INPUT goes here unless we're doing C++ %+ C++ definition Note the "fread()/read() definition of YY_INPUT goes here". Well, after building I note that the fread definition is actually there (in zend_language_scanner.c), but I can't manage to understand _where on earth did it come from_. Doing a full text search on all project files' didn't help. Any help would be really appreciated. Regards, Ernesto PS: I'm building on Win32, but I don't think that's relevant.
