Various distros. Tested on these:
* Debian testing/unstable (with recent updates)
$ lsb_release -a
Distributor ID:	Debian
Description:	Debian GNU/Linux 9.0 (stretch)
Release:	9.0
Codename:	stretch

$ gcc --version
gcc (Debian 6.3.0-8) 6.3.0 20170221

* Debian stretch cross compilation to sparc64
$ sparc64-linux-gnu-gcc --version
sparc64-linux-gnu-gcc (Debian 6.3.0-9) 6.3.0 20170316

* openSUSE Tumbleweed (with recent updates)
$ lsb_release -a
LSB Version:	n/a
Distributor ID:	openSUSE
Description:	openSUSE Tumbleweed
Release:	20170311
Codename:	n/a

$ gcc --version
gcc (SUSE Linux) 6.3.1 20170202 [gcc-6-branch revision 245119]

Error is:
rpc_server.c: In function ‘main’:
rpc_server.c:78:2: warning: implicit declaration of function ‘pmap_unset’ [-Wimplicit-function-declaration]
  pmap_unset(program, version);

But maybe I'm wrong, doing some mistake.

Kind regards,
Petr
