I brought over Eric's change to gnulib:
2006-03-04 Eric Blake <ebb9@xxxxxxx>
* strerror_r.m4 (AC_FUNC_STRERROR_R): Avoid unused variable warning.
*** m4/strerror_r.m4.bak 2005-01-26 17:51:26.000000000 +0100
--- m4/strerror_r.m4 2006-04-24 00:36:14.000000000 +0200
***************
*** 25,30 ****
--- 25,31 ----
char buf[100];
char x = *strerror_r (0, buf, sizeof buf);
char *p = strerror_r (0, buf, sizeof buf);
+ return !p || x;
]])],
ac_cv_func_strerror_r_char_p=yes)
