Already defined symbols

[Claudio Alberti]

Hi all,
        I'm trying to compile Flex/Bison generated files under Win32 with
Visual C++ 6.0. Now I'm struggling with these linking errors.

lex.yy.obj : error LNK2005: _yylex already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yyrestart already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_switch_to_buffer already defined in
sil.tab.obj
lex.yy.obj : error LNK2005: _yy_load_buffer_state already defined in
sil.tab.obj
lex.yy.obj : error LNK2005: _yy_create_buffer already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_delete_buffer already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_init_buffer already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_flush_buffer already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_scan_buffer already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_scan_string already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yy_scan_bytes already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _comment already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _count already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _dumpline already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _all_lines already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yycol already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yyline already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yyout already defined in sil.tab.obj
lex.yy.obj : error LNK2005: _yyin already defined in sil.tab.obj

They all seem to have the same origin but I can't figure out it. All these
functions/variables are only present in lex.yy.c, so why a definition is
said to be already present in sil.tab.obj?
Has anyone ever faced anything like this?
Thank you,
Claudio
