+ + correct configure version-check/warnng for g++ to allow for 10.x
+ + re-enable "bel" in konsole-base (report by Nia Huang)
+ + add linux-s entry (patch by Alexandre Montaron).
+ + drop long-obsolete convert_configure.pl
+ + add test/test_parm.c, for checking tparm changes.
+ + improve parameter-checking for tparm, adding function _nc_tiparm() to
+ handle the most-used case, which accepts only numeric parameters
+ (report/testcase by "puppet-meteor").
+ + use a more conservative estimate of the buffer-size in lib_tparm.c's
+ save_text() and save_number(), in case the sprintf() function
+ passes-through unexpected characters from a format specifier
+ (report/testcase by "puppet-meteor").
+ + add a check for end-of-string in cvtchar to handle a malformed
+ string in infotocap (report/testcase by "puppet-meteor").

+ + 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.
