Hello Rainer,

thanks for the bug report.

I can reproduce these failures.

The depcomp6.test one looks like bad interaction between AC_PROG_CC_C_O
and AM_PROG_CC_C_O, or a shell bug: although the compiler is deemed
potent by the former, the latter still rewrited $CC to prepend the
'compile' script:

Can you try the patch below?  If it works for you, I will put this
(master and branch-1-10); also put you in THANKS if you don't mind.

The other two are libtool bugs; I will address them later:
