ecpg glitch in CVS tip

I'm seeing this:

make[4]: Entering directory `/home/postgres/pgsql/src/interfaces/ecpg/ecpglib'
...
gcc -O1 -fno-strict-aliasing -g -Wall -Wmissing-prototypes -Wmissing-declarations  -fpic -DFRONTEND

descriptor.c: In function `ECPGset_desc':
descriptor.c:460: warning: assignment from incompatible pointer type

...

Looks like that last patch needs a bit o' work yet ...
