Your link command indicates that you are not using the gethostbyname() 
routine from DECC$SHR or the TCPIP$LIB.OLB for some reason.

The current 7.3-1 DECC$SHR has definitions for two variants of 
gethostbyname(), one is a BSD44 flavor.

I do not know if a C RTL ECO kit will add the routines to your older 
release of OpenVMS.

There is also a gethostbyname routine in TCPIP$LIBRARY:TCPIP$LIB.OLB.

As John suggested, to resolve that symbol, you can add the 
TCPIP$LIBRARY:TCPIP.OLB/LIB to your link command line as a work around.

Then you should not need the MY_GETHOSTBYNAME module either.

The quoting in this thread has gotten a bit confused.  I think that the 
TCPIP$LIBRARY option will only work if you have the HP TCPIP product 
installed.

For help linking with Multinet, you will need to contact them.  Their 
developers sometimes post here, and there is also a vmsnet newgroup for 
Multinet.  vmsnet.networks.tcp-ip.multinet

Search the source code and the user and system supplied header files to 
determine how they are used.

Sometimes just changing an option in CONFIG.H can make these problems go 
away, or you may not have compiled or linked in a module that you need.

>>Will they be a problem when running the images?

Probably.
