+ + further workaround for PIE/PIC breakage which causes gpm to not link.
+ + fix most cppcheck warnings, mostly style, in ncurses library.

+ + improved manual page description of tset/reset versus window-size.
+ + fixes to work with a slightly broken compiler configuration which
+ cannot compile "Hello World!" without adding compiler options
+ (report by Ola x Nilsson):
+ + pass appropriate compiler options to the CF_PROG_CC_C_O macro.
+ + when separating compiler and options in CF_CC_ENV_FLAGS, ensure
+ that all options are split-off into CFLAGS or CPPFLAGS
+ + restore some -I options removed in 20140726 because they appeared
+ to be redundant. In fact, they are needed for a compiler that
+ cannot combine -c and -o options.
