+ + update version-check for gnat to allow for gnat 10.x to 99.x
+ + fix an uninitialized variable in lib_mouse.c changes (cf: 20200502)
+ + add a check in EmitRange to guard against repeat_char emitting digits
+ which could be interpreted as BSD-style padding when --enable-bsdpad
+ is configured (report/patch by Hiltjo Posthuma).
+ + add --disable-pkg-ldflags to suppress EXTRA_LDFLAGS from the
+ generated pkg-config and ncurses*-config files, to simplify
+ configuring in the case where rpath is used but the packager wants
+ to hide the feature (report by Michael Stapelberg).
+ > fixes for building with Visual Studio C++ and msys2 (patches by
+ "Maarten Anonymous"):
+ + modify CF_SHARED_OPTS to generate a script which translates linker
+ options into Visual Studio's dialect.
+ + omit parentheses around function-names in generated lib_gen.c to
+ work around a Visual Studio C++ limitation.
