It would appear that you are doing your build in the same directory as
your sources. Not everyone does this.

If you were to make cvs with the following recipee:

   tar xzf cvs-1.12.9.tar.gz
   cd cvs-1.12.9
   mkdir obj.`uname -s`
   cd obj.`uname -s`
   ../configure
   make

(which many folks use to allow them to build multiple architecure
versions of cvs from the same set of sources) you would see

  ... gcc -DHAVE_CONFIG_H -I. -I../../src -I.. -I../../lib -I../lib 
-I../../diff -I../../zlib ...

so that there are NOT two -I. switches based on the value of $(srcdir)

Further digging shows the src/Makefile.in contains:

COMPILE = $(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) \
        $(CPPFLAGS) $(AM_CFLAGS) $(CFLAGS)

as well as:

DEFAULT_INCLUDES =  -I. -I$(srcdir) -I$(top_builddir)

the -I. is needed when $(srcdir) != `pwd` to allow some derrived files
to be included in the directory as a general autoconf feature.

        Enjoy!
