I had a similar problem with MySQL 4.x source code: the use of #pragma interface and #pragma 
implementation could lead to defining interfaces to constructors, without defining them in the 
code (implementation).

I fixed them adding code like

#ifdef __GNUC__
template class I_List<i_string>;
#endif

at end of some files. Unfortunately class name depends on sources used, YMMV.

OS/2's host.exe seems to be a braindead version of Unix/Linux host,
without any of the options.  Type 'host os2ports.com' and it tells you 
os2ports.com = 65.75.16.114

I'm not sure what to make of hostid.exe.  'hostid.exe' returns  
  Hostid = 127.0.0.1
'hostid.exe xxx' returns
  Usage: hostid <a.b.c.d>  - sets the hostid to a.b.c.d IP address
  Usage: hostid  - displays the hostid of the machine  

I doubt if either one of them is very useful.

"host" actually seems to be some kind of a stripped down version of 
"dig", which is part of the ISC BIND package.

"hostid" is not present in BSD -- at least not in Open- or FreeBSD. 
Besides OS/2, it probably exists on Linux systems.
