At the end of each test compile autoconf macros endeavour to clean up
the rubbish with a 'rm -f conftest.*'
The current Apple versions of gcc can build fat object files when
given multiple -arch options as might be done with CFLAGS="-O2 -g -
arch i386 -arch ppc" Since not long after the libtool 1.5.22 release
these -arch options have been correctly handled in libtool/autoconf
build systems.
However, in order to build the fat binaries, the compiler driver
creates a directory conftest.dSYM to hold the intermediate object
files before they are combined with lipo. The standard cleanup
command does not remove this directory.
To reproduce this, take any autoconf package on MacOS or Darwin. Set
CFLAGS as above and run configure.
You will see lines in the log and console output like:
checking for ANSI C header files... rm: conftest.dSYM: is a directory
rm: conftest.dSYM: is a directory
yes
I presume this just needs a 'rm -rf' in the appropriate place.
