test for t1lib version fails

Dear All,

the check for version of system t1lib fails with beta 2.96.3,
since libs/t1lib/t1lib.ac sets

  CPP="$CPP $EXTRA_LIBT1_INCLUDE"

while AC_TRY_RUN autoconf macro uses $CPPFLAGS.
Thus compilation fails as "t1lib.h" can not be included (not found).
(I did not rerun autoconf, but used configure script as distributed.)

Also ncurses library is now at 5.4, while tetex beta has 5.3.
xpdf in tetex-src-beta-2.96.3 is 2.02, one major version number
behind the development (www.foolabs.com has version 3.00).

                 Sincerely, Michail
