SGI mode depcomp breaks when '.' appears in source filenames twice

[Robert Boehne]

Automake:

I've been having some problems with depencency tracking under
IRIX with the native compiler, it didn't help to use GNU sed,
so I tracked the problem down to this line from depcomp:

 sed 's/^[^\.]*\.o://' | tr '
...

For a source file named ExprIntrp.tab.c, the dependency file
produced has this for it's contents:

ExprIntrp.tab.lo : \
ExprIntrp.tab.o: /usr/include/stdio.h /usr/include/standards.h
/usr/include/sgidefs.h /usr/include/alloca.h #:fec /usr/include/stdio.h
:
/usr/include/standards.h :
/usr/include/sgidefs.h :
/usr/include/alloca.h :
#:fec :

The problem is the appearance of 'ExprIntrp.tab.o:' on the second
line, this is intended to be stripped out, and is if the
sed command from depcomp is altered to
  sed 's/^[^\.]*\.tab.o://'
But that, of course, is not the fix.

Could a sed guru suggest a fix for this particular problem?

Thanks,

Robert
