factor out workaround for XTSTRINGDEFINES as CF_CONST_X_STRING

The check for _DEFAULT_SOURCE should apply to "recent" Cygwin (since early 2016),
and except for "NEWLIB" vs "GLIBC" in the test, acts the same if I pretend
that "newlib" is the GNU C library. Without this, the check falls through
to the _XOPEN_SOURCE test, which breaks the pseudoterminal checks for xterm.

dnl CF_CONST_X_STRING version: 1 updated: 2019/04/08 17:50:29
dnl -----------------
dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
dnl character-strings.
dnl
dnl It is ambiguous because the specification accommodated the pre-ANSI
dnl compilers bundled by more than one vendor in lieu of providing a standard C
dnl compiler other than by costly add-ons. Because of this, the specification
dnl did not take into account the use of const for telling the compiler that
dnl string literals would be in readonly memory.
dnl
dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
dnl let the compiler decide how to represent Xt's strings which were #define'd.
dnl That does not solve the problem of using the block of Xt's strings which
dnl are compiled into the library (and is less efficient than one might want).
dnl
dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
dnl when compiling the library and compiling using the library, to tell the
dnl compiler that String is const.

dnl POSIX documents test-macros which an application may set before any system
dnl headers are included to make features available.
dnl
dnl Some BSD platforms (originally FreeBSD, but copied by a few others)
dnl diverged from POSIX in 2002 by setting symbols which make all of the most
dnl recent features visible in the system header files unless the application
dnl overrides the corresponding test-macros. Doing that introduces portability
dnl problems.
dnl
dnl This macro makes a special check for the symbols used for this, to avoid a
dnl conflicting definition.
