+ trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with Leon Winter). + trim some obsolete/incorrect wording about EINTR from wgetch manual page (patch by Leon Winter). + really correct 20100515 change (patch by Rich Coe). + add "--enable-string-hacks" option to test/configure + completed string-hacks for "sprintf", etc., including test-programs. + make "--enable-string-hacks" work with Debian by checking for the "bsd" library and its associated "<bsd/string.h>" header.
