HELP in Visual C++ when adding .c files

Hi,

I created with Yacc and Lex on a computer with LINUX three files for a parser:
y.tab.c
y.tab.h
lex.tab.c

My parser is working greatly on the linux computer.

But when I add these three files to my Visual C++ 5.0 project, I get two errors when building : fatal error C1010: unexpected end of file while looking for precompiled header directive

Could you help, please.

Best Regards
