I'll ignore that the results weren't *exactly* the same.

If you're looking for simple, try:

        CC=gcc -Wall -g -ansi
        CFLAGS=`pkg-config --cflags gtk+-2.0`
        LDFLAGS=`pkg-config --libs gtk+-2.0`
        EXES=base
        
        all: $(EXES)
        
        clean:
                rm -f $(EXES)
        
For a single source file with no object dependencies, this should work
every time. (This Makefile won't capitalize the executable name like
yours, in case that was important to you.) But, for the record, I
copy/pasted your Makefile and had no trouble or warnings compiling with
it, except for the "--libs" bit.
