internal headers must be before system headers

[candrsn@…]

same problem in stock Cygwin install and in Solaris 2.7
and all systems with gif header in /usr/local/include

in frmts/gis/GNUmakefile

%.o:    %.c
        $(CC) -c $(GDAL_INCLUDE) $(CFLAGS) $(XTRA_OPT) $*.c -o $*.o


XTRA_OPT must come before normal headers, otherwise gif headers in
/usr/local/include will be picked up.


%.o:    %.c
        $(CC) -c $(XTRA_OPT) $(GDAL_INCLUDE) $(CFLAGS) $*.c -o $*.o

Carl, 

I updated the three implicit rules in frmts/gif/GNUmakefile as you suggested.
