Subject: [PATCH] ncurses 6.1 - patch 20190623

+ improve the tabs.1 manual page to distinguish the PWB/Unix and 7th
  Edition versions of the tabs utility.
+ add configure check for getenv() to work around implementation shown
  in Emscripten #6766, use that to optionally suppress START_TRACE
  macro, whose call to getenv() may not work properly (report by Ilya
  Ig Petrov).
+ modify initialization functions to avoid relying upon persistent
  data for the result from getenv().
+ update config.guess, config.sub

+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.
