I'm using autoconf 2.61 on cygwin where my home directory is "/home/Paul
Brannan". I have a project located in my home directory which uses
automake.
When I run configure, I see:
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
/home/Paul: /home/Paul: is a directory
configure: WARNING: `missing' script is too old or missing
The problem is that $srcdir and $am_aux_dir are not quoted when they are
used.
I have worked around this bug by post-processing the configure script
after autoconf is run.
