Unfortunately, I'm now able to compile zsh but not link it:

Modules/termcap.o: In function `scantermcap':
/usr/src/local/zsh/zsh-4.0-build/Src/Modules/../../../zsh-4.0/Src/Modules/termcap.c:320:

Modules/termcap.o: In function `boot_zshQstermcap':
/usr/src/local/zsh/zsh-4.0-build/Src/Modules/../../../zsh-4.0/Src/Modules/termcap.c:366:

This appears to happen because the checks to add the library containing
boolcodes, et al. to LIBS were removed, but the checks for whether those
variables are defined and which headers define them were NOT removed.

In any case AC_TRY_COMPILE is the wrong way to detect boolcodes, etc.
AC_TRY_LINK is better; that way even if the header happens to be there,
but the library is not, they won't be marked as available.

The following patch gets my compile and link going, but of course does
not enable $terminfo or echoti on my system, and uses the fallback lists
of capcodes for $termcap.  However, I don't know whether to add

AC_SEARCH_LIBS(setupterm, ...)

or

AC_SEARCH_LIBS(tigetstr, ...)

or both.
