Hi Peter,
The recommended way, copy/past as is, does not works. I have to add explicitly
--disable-dependency-tracking
So, the command line become :
./configure --prefix=/opt/gsl/gsl-1.14-Leopard --disable-shared
--disable-dependency-tracking CC=gcc CFLAGS='-isysroot
/Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5 -arch i386 -arch ppc'
LDFLAGS='-arch i386 -arch ppc'
Thanks Brian for the update of documentation, that's usefull for Mac users.
Have a nice week-end, Eric

The recommended way is to set the flags at configure commandline. Could you
please try if the following also works:
./configure --prefix=/opt/gsl/gsl-1.14-Leopard --disable-shared CC=gcc
CFLAGS='-isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5
-arch i386 -arch ppc' LDFLAGS='-arch i386 -arch ppc'

The INSTALL file comes from autoconf, so if any changes are needed we should
probably report it upstream. IIUC, there is some code in automake to detect
multi arch builds in order to turn off dependency tracking automagically. I'm
not sure, however, whether you need to give *FLAGS at configure commandline or
if the detection is supposed to work also when taken from the environment.
Therefore, it would be useful to know if the configure call I described above
works for you, or not.
Thanks,
Peter
