Yes that helped; LongStrings were ON in the UART module.  When I  changed that 
to OFF, the error report changed to:

Main.pas:(.text.n_main_$$_main$$longint+0xa): undefined reference to 
`fpc_shortstr_to_shortstr'

Which suggested to me I needed to link the object containing 
fpc_shortstr_to_shortstr explicitly as I am using the gcc make file.
After a bit for searching I found the export in system.o which had been 
generated by the embedded compiler.  Adding this to the make file resolved the 
the remaining error.

Sven, thank you for pointing me in the right direction!

Kind regards,

Paul
