Yes, I forgot about that, sorry.  But the output of "gcc -v" always
shows where the files are.

> As you suggest 'nm -A lsbfnew.o' gives:

No lsbfnew.o is not what is of interest.  Please do this for ipmpar.o,
because dcdflib.o seems to be unable to find the function ipmpar
defined in ipmpar.c.  I want to see what symbols are in ipmpar.o when
it is compiled with and without -g.

Some explanation of this output is given in section 8.9 of the DJGPP
FAQ list.  In a nutshell, all the symbols markes with `T' are
functions defined in this module, while symbold marked with `U' are
symbols this module references (e.g., a function call) but does not
define.  For example, the above shows that lsbfnew.c defines a `main'
function and calls `fopen', `fscanf', `log' and others.

What I'm looking for is to see whether ipmpar.o lists the function
ipmpar (symbol name "_ipmpar") with `T'.
