Error running gda-buildclient (with patch)

[Brian Jepson <bjepson home com>]

I tried to run gda-buildclient, but ran into a few problems with the
following test case:

export prefix=/usr 
export CC=gcc 
gda-buildclient --f gda-client-test12.c --o gda-client-test12

Here are the problems:

   * The following error message occurs when I use it:

     /usr/bin/gda-buildclient: test: o: integer expression expected
     /usr/bin/gda-buildclient: test: =: unary operator expected

   * It assumes that $CC and $prefix are set without checking them.
 
   * It does not have a complete list of includes necessary to build an
     app (my test case was gda-client-test12.c)

   * -lgda-clnt should be -lgda-client

   * if --o is unspecified, it overwrites the input file

   * test for $target fails with:

      ./gda-buildclient: test: =: unary operator expected
      ./gda-buildclient: test: =: unary operator expected

I've included a patch that corrects these problems:
