We have some problems building current CVS heads with tgolem on an IRIX

Any ideas how to fix these issues, especially the gethostbyname_r one?
Guess you found it already but did you see patch to fix these issues on
other platforms from Andreas Tobler recently:
http://lists.gnu.org/archive/html/commit-classpath/2006-08/msg00272.html
Looks like it didn't fix it for IRIX but maybe he has some ideas?
Problem is, that only linux, darwin and FreeBSD support a usable flag
for this kind of call. I did not find a solution for other archs and my
sparc and hpuxen will also fail when cp gets reimported to gcc.
I tried to pass 0 for these platforms but I was told to error instead.

I also tried to suggest to:
#ifndef MSG_NOSIGNAL
signal (SIGPIPE, SIG_IGN);
#endif
...
But this was also not a good solution....
So far I have no more suggestions.
For the gethostbyname_r case, IRIX uses 5 arguments:
int gethostbyname_r(char *hostname, struct hostent *hostent, char
*buffer, int buflen, int *h_errnop)
Here you could modify the call to gethostbyname_r like this:
#ifdef IRIX
ret = gethostbyname_r (hostname, &hret, buf, buflen, &herr);
#endif
This part needs to be modified as well, and I see I need to do that
anyway since in case we call gethostbyname we do not have a proper
result......
if (ret != 0 || result == NULL)
{
if (herr == ERANGE)
{
buflen *= 2;
JCL_free(env, buf);
continue;
}
JCL_free(env, buf);
return -herr;
}
While Linux and others use the 6 argument variant:
int gethostbyname_r(const char *name, struct hostent *ret, char *buf,
size_t buflen, struct hostent **result, int *h_errnop)
Btw, AIX4, Digital Unix/Tru64, HPUX 10 use three arguments:
int gethostbyname_r(char *hostname, struct hostent *hostent, struct
hostent_data *data)
So far comments.
hth,
