On IRIX 6.5, the strsignal replacement fails to compile:
"strsignal.c", line 69: error(1143): declaration is incompatible with
"char *_sys_siglist[]" (declared at line 176 of
"///usr/include/signal.h")
static const char *_sys_siglist[NSIG];
^
"strsignal.c", line 150: error(1166): expected a declaration
} while (0);
^
This should fix it:
2008-04-11 Bruno Haible <[EMAIL PROTECTED]>
* lib/strsignal.c (_sys_siglist): Don't declare if already declared.
(init): Fix syntax error.
* m4/strsignal.m4 (gl_PREREQ_STRSIGNAL): Check whether _sys_siglist
is declared.
