ecpg glitches in Feb 23rd beta.

1. ecpg Makefiles have hard-coded gcc-only options hard coded.

2. ecpg/preproc/Makefile trashes CFLAGS instead of appending to it.

3. ecpg/preproc/preproc.y has duplicate S_SIGNED

Patch appended to fix #1-#3 for Michael's review.  Don't appear to
break anything else, but I'm not the one working on this.

4. ecpg/preproc/preproc.y has an illegal assignment between "void*" 
   and "const char*".  Log of the make error is...
   
gmake -C preproc all
gmake[3]: Entering directory `/ceo/darrenk/pgsql63d/src/interfaces/ecpg/preproc'
xlc -I../../../include -I../../../backend -I/gnu -qchars=signed -qmaxmem=8192 -qhalt=w -qsrcmsg  -I../include -DMAJOR_VERSION=1 -DMINOR_VERSION=0 -DPATCHLEVEL=0   -c y.tab.c -o y.tab.o
      289 |         free(yyvsp[-2].type.name);
            ...........................a......
a - 1506-280 (E) Function argument assignment between types "void*" and "const char*" is not allowed.
gmake[3]: *** [y.tab.o] Error 1

This one I don't know how to fix.  I just commented ecpg out of the
interfaces make and all else went a-ok.
