Has anyone using Microware's Level I 6809 C Compiler
ever seen anything like this?
The Linker reads the .r files and the Library,
then prints out a dozen lines of the form:

Missing Symbol	Ref'ed in	In file
_11		mused_c		mused.r
_52		mused_c		mused.r
_123		mused_c		mused.r

etc.

Now, mused.c is the file containing only my main() program
and nothing else (the word "mused" doesn't even appear
inside it).

I've seen lots of legitimate linker errors, when a function
or external variable couldn't be found (these were listed
by name and easily recognized), but never any
_<number> symbols.  I know the intermediate Assembler
code uses labels in the underscore-number format.
Some theories:

(1) These are calls to mult, divide, etc. routines
and the library is braindamaged and doesn't supply them.

(2) These are external constants made up by the compiler
that somehow got lost.

(3) One of the compiler phases screwed up and put out
a bogus intermediate file.  Sometimes the phases
do mis-load from CMDS/ and when that happens they either
crash or sometimes write bad output that the next phase
*usually* chokes on.  Funny, OS9 isn't supposed to load
disk files with bad CRCs -- the bytes must get hosed
during or after being written to RAM.

I'd appreciate hearing from anyone who has seen this style
of error and can save me from re-inventing the wheel.

I plan to re-compile the main program (mused.c) and try
again.  It had been only slightly modified since the last
good compile/link.

Also, is "ident" supposed to work on C libraries?
It always gives me "incorrect header" error.
Is that normal?  Ident works fine on "os9boot".

Thanks, mike k
