Hi there,

there is a problem in libtool 2.4.2 that causes several libtool autoconf =
tests to generate spurious output on Mac OS X, like this:

[...]
checking for archiver @FILE support... rm: cannot remove =
`conftest.dSYM': Is a directory
no
checking for strip... strip
checking for ranlib... ranlib
checking command to parse /usr/bin/nm output from cc object... rm: =
cannot remove `conftest.dSYM': Is a directory
ok
[...]

It is well-known that the Mac OS X compilers generated "conftest.dSYM" =
directories with debug information under certain circumstances. See also =
this libtool discussion from 2007: =
<http://old.nabble.com/Mac-OS-X-Leopard-and-conftest.dSYM-directories-td13=
681269.html>

Now libtool already worked around this OS X behavior by changing =
instances

  rm -f conftest*

to

  rm -rf conftest*

However, it appears that three instances of this in libtool.m4 where =
overlooked or crept in at a later date. The attached patchs (one for =
2.4.2, one for git) corrects that. Without this patch, the spurious =
autoconf output can lead to various issues; e.g. it causes hard test =
suite errors in automake 1.12.x.


Since this affects many, many projects out there using libtool, it would =
be nice if this could be fixed in a released version of libtool.=20


Thanks,
Max

Sorry, I just realized that there are far more than three places where =
this problem occurs. The attached revised patch tries to address that.

Note that I did not attempt to unify the use of $RM  vs.  "rm -f", as I =
don't know whether there is any logic behind the current seemingly =
random switching between the two. And there are some instances left in =
autoconf, too. Will report those separately.

Cheers,
Max
