    patch 8.2.3406: on some systems tests fail without _REENTRANT

    Problem:    On some systems tests fail without _REENTRANT. (Elimar
                Riesebieter)
    Solution:   Add -D_REENTRANT in configure. (closes #7402)

+dnl On some systems REENTRANT needs to be defined.  It should not hurt to use

 dnl gcc 3.1 changed the meaning of -MM.  The only solution appears to be to
 dnl use "-isystem" instead of "-I" for all non-Vim include dirs.
 dnl But only when making dependencies, cproto and lint don't take "-isystem".
