+ correct parsing of relative tab-stops in tabs program (report by
Philip Ganchev).
+ adjust configure script so that "t" is not added to library suffix
when weak-symbols are used, allowing the pthread configuration to
more closely match the non-thread naming (report by Werner Fink).
+ modify configure check for tic program, used for fallbacks, to a
warning if not found. This makes it simpler to use additonal
scripts to bootstrap the fallbacks code using tic from the build
tree (report by Werner Fink).
+ fix several places in configure script using ${variable-value} form.
+ modify configure macro CF_LDFLAGS_STATIC to accommodate some loaders
which do not support selectively linking against static libraries
(report by John P. Hartmann)
+ fix an unescaped dash in man/tset.1 (report by Sven Joachim).

dnl -Wredundant-decls (system headers make this too noisy)

dnl -Wtraditional (combines too many unrelated messages, only a few useful)

dnl -Wwrite-strings (too noisy, but should review occasionally). This

dnl is enabled for ncurses using "--enable-const".
