A testcase in C:

[hjl@gnu-6 tmp]$ echo  b.c
[hjl@gnu-6 tmp]$ gcc -g -c -O2 b.c 
[hjl@gnu-6 tmp]$ objcopy --compress-debug-sections b.o
BFD: b.o: unable to initialize commpress status for section .debug_line
objcopy:b.o: Invalid operation
[hjl@gnu-6 tmp]$

[Bug gold/14309] gold doesn't build with gcc 4.1.3

That is not a documented minimum is still that 4.1.3 and until gdb_index.cc
stuff has been added it worked just fine.  GCC 4.1.x is still widely deployed
as a system compiler, and having very high GCC requirements is
counter-productive, you usually need to build new binutils in order to build
new gcc, with this requirement you are forcing everybody to first build new
binutils without gold, then new gcc, then build again new binutils and possibly
build new gcc again.
