As you said, it isn't much work.

Attached is a patch with a small amount of documentation but lacking a
ChangeLog entry. I'm sending it now already for you to comment on.

A usage example :
dannypc: {49} make
/home/danny/src/gcc/svn@gcc.gnu.org/build/gcc/xgcc
-B/home/danny/src/gcc/svn@gcc.gnu.org/build/gcc --coverage -c t.c
-fcoverage-base=/tmp  -o t1.o
/home/danny/src/gcc/svn@gcc.gnu.org/build/gcc/xgcc
-B/home/danny/src/gcc/svn@gcc.gnu.org/build/gcc --coverage -c t.c -o
t2.o
strings t1.o >t1.strings
strings t2.o >t2.strings
dannypc: {50} more *.strings
::::::::::::::
t1.strings
::::::::::::::
e304
Hello, world !
/tmp/t1.gcda
::::::::::::::
t2.strings
::::::::::::::
e304
Hello, world !
/home/danny/t/t2.gcda
dannypc: {51} 

If I need to change the implementation in some way, please advise.

	Danny
