lib/ChangeLog:
2006-06-16 Eric Blake <[EMAIL PROTECTED]>
* unsetenv.c [!defined errno]: Assume errno.h declares errno.
* unicodeio.c [!defined errno]: Likewise.
* strtod.c [!defined errno]: Likewise.
* strtol.c [!defined errno]: Likewise.
m4/ChangeLog:
2006-06-16 Eric Blake <[EMAIL PROTECTED]>
* rmdir-errno.m4 (gl_FUNC_FMDIR_NOTEMPTY): Assume errno.h declares
errno.
