Change the first lines to

#ifndef LCD_H
#define LCD_H

Since you cannot use . in #if.. macros you'll replace it with an _ (of course, this is only one way)

You don't normally use dots in identifiers.

The defined name must be a regular identifier, containing only a-z, underscore and 0-9 characters but not beginning with a number. In

#define LCD.h

LCD is considered to be the "identifier", and the rest of it is junk text (hence the extra text warning).
