Feedback on GM2 error messages

[Michael Riedl]

Gaius,

just translating some foreign code to Modula-2 to get rid of some 
copyrighted code in my numerical library. Normally I first run such code 
after the first conversion through XDS M2 as GM2 (in the past) made 
quite some error messages which where hard to understand or pointed to 
wrong line numbers in the code.

By fortune XDS crashed during the first compilation without any hint 
what went wrong (a unmatched "{{" in a spoiled constant vector 
declaration). Hence I used GM2 for the first round of compilations.

The error messages have significantly improved and where helpful in 
removing the "usual" stuff going wrong - typos, case mismatch, wrong 
symbols etc. etc.

Many thanks for these improvements !!!

Gruß

Michael
