Re: --with-tcl build on AIX (and others) fails

I tried out the patch that Andreas sent in a couple weeks ago, and find
that as-is it fails on HPUX.  The attached version works okay on both
HPUX 10.20 and RH Linux 7.2, however.  Anyone want to try it on other
platforms?  (Note this only covers Andreas' proposed changes for pltcl,
not for libpgtcl.)

            regards, tom lane
