You fixed the first portability problem: the function is missing on some platforms. But there is another one. I want to use the replacement in GNU clisp, so I did "man strsignal", and it says: "On some systems (but not on Linux), a NULL pointer may be returned instead for an invalid signal number." And it's even worse than that: for negative or out-of-range signal numbers, * Solaris strsignal returns NULL, * AIX 5.1 strsignal returns (char*)(-1) ! As a user of this function, I don't want to special case these return values. The function should always return a reasonable pointer. So I propose to change the module so that, on these two platforms, it overrides the system function. Do you agree? May I do this? Do you want to do it?
