  Using CVS repository 
I tried to compile the current tree,

  First, I wolud like to state that indeed configure works without problems !

  Second, I wanted to use  -gstabs option instead of -g 
(the is a line count limitation with -g that is overflooded)

  I am using gcc 2.952 with DJGPP 2.03

  but changing "CFLAGS= -g -O" into  "CFLAGS=-gstabs -O"
leads to an unexpected and unnice result :

  The labels used for the stabn generation of source line encoding are labeled
by
   LM???
where ??? represents a number,

  the problem is that gcc only considers .L???? labels as local labels
thus it keep all these LM??? labels
and when debugging  gdb with itself a backtrace gives 
a list of LM??? without args :(

  Does anyone have an idea what is wrong here ???

I am quite sure it worked better with older gcc versions !!
(I tested gcc v 2.951 but this one also generates LM???)
