That should be
int main( void )
(main() is supposed to retur an int and take either no arguments
or an int and an array of char pointers, but not an unsoecified
number of arguments).

What is the 'static' meant to be good for? Also without
it this will create an array that is read-only. 'static'
only is necessary if you want a variable that "survives"
the end of the function and thus still exists (with the
previous value) when you call the function another time.

The problem is that this should be something like
const struct LVC some_name[ 4 ] = {
and then the compiler should accept it. That's because
the type is 'struct LVC' and you're creating a strange
mix out of the type name and the variable name.

I hope you use it as a C and not a C++ compiler, otherwise
you'd better ask in comp.lang.c++.

There's nothing in the program you psoted that would require
the inclusion of any header files.
