Looks ok.

I applied your changes to unsetenv.c, strtol.c (shared with GNU gettext)
and unicodeio.c (for which I'm responsible), and this extra patch:


2006-06-17  Bruno Haible  <address@hidden>

      * setenv.m4 (gl_PREREQ_SETENV, gl_PREREQ_UNSETENV): Remove test
      whether errno is declared. Assume <errno.h> declares errno.
