Unfortunately I do, because otherwise different instances of texi2dvi
running in parallel can still racily stomps on each other feet:
mkdir: cannot create directory `.../doc/doc!automake-history.t2d/tex_help':
File exists
/usr/bin/texi2dvi: cannot create directory:
../doc/doc!automake-history.t2d/tex_help
This is likely due to this bit of botched code in the texi2dvi script (version
4.13):
# ensure_dir DIR1 DIR2...
# -----------------------
# Make sure the directories exist.
ensure_dir ()
{
for dir
do
test -d "$dir" \
|| mkdir "$dir" \
|| error 1 "cannot create directory: $dir"
done
}
So I say we stay dumb and safe, and keep the patch as is.
