Seems so.  I thought it was not needed because when
AM_PROG_CC_C_O decides `compile' is required, it is also used
when compiling libtool objects.  However perhaps I was wrong,
because `compile' does something only for *.o and *.obj files,
it is a no-op for *.lo files.

Maybe we need to tell AM_PROG_CC_C_O about *.lo files.

To makes matter worse, because AM_PROG_CC_C_O horribly
overwrites CC, it's not clear to me whether


is equivalent to 


It looks like Libtool's `-c -o' check would not give the same
answer.  I haven't dug all this; I think Ralf W sent some mail
about it, but I haven't flushed all my mails yet.

I agree it would be better to set down a common lock scheme,
although that really should not hold any release.
