While it is true that all I require is the filename, MPE needs a complete
compilation unit entry in the SOM. 

The compilation unit is:

struct compilation_unit {
        union name_pt    name; 
        union name_pt    language_name; 
        union name_pt    product_id; 
        union name_pt    version_id; 
        union name_pt    copyright; 
        struct sys_clock compile_time; 
        struct sys_clock source_time; 
}; 

Since I must create the entire entry, it is best to make it mean something
legitimate, so I chose to include the compiler information and version in
the meta command as in:

; gcc_compiled.:
   .compiler "hello.c GNU_C_Compiler egcs-2.91.52 19980727 (gcc2 ss-980609
experimental)"

This yields:

/OFFICIAL/PUB/ODUMP -compunit ./a.out

I'm not sure what would happen to MPE's tools if they found an incomplete
compilation
unit, but it is better to be complete, IMHO.
