Subject: ncurses 5.7 - patch 20091121
X-Git-Tag: v5.8~61
X-Git-Url: http://ncurses.scripts.mit.edu/?p=ncurses.git;a=commitdiff_plain;h=582d14ba03080cfa0bd9c745fbae8c21089bc936;ds=sidebyside

ncurses 5.7 - patch 20091121

+ fix case where progs/tput is used while sp-funcs is configure; this
  requires save/restore of out-character function from _nc_prescreen
  rather than the SCREEN structure (report by Charles Wilson).
+ fix typo in man/curs_trace.3x which caused incorrect symbolic links
+ improved configure macros CF_GCC_ATTRIBUTES, CF_PROG_LINT.
