I beg to differ, at least some of them don't come from configure.*. One
example is
http://people.debian.org/~geissert/source-bashisms/evolution_2.30.1.2-2.dsc where I can't really fine the >&$3 call (nor any >& for that matter) in the configure.* files.
And here, just a quick test shown that:
corsac@hidalgo: grep -c '>&' /usr/share/*/config.{guess,sub}
/usr/share/automake-1.11/config.guess:13
/usr/share/automake-1.7/config.guess:13
/usr/share/misc/config.guess:13
/usr/share/automake-1.11/config.sub:5
/usr/share/automake-1.7/config.sub:5
/usr/share/misc/config.sub:5
corsac@hidalgo: dpkg -S /usr/share/*/config.{guess,sub}
automake: /usr/share/automake-1.11/config.guess
automake1.7: /usr/share/automake-1.7/config.guess
autotools-dev: /usr/share/misc/config.guess
automake: /usr/share/automake-1.11/config.sub
automake1.7: /usr/share/automake-1.7/config.sub
autotools-dev: /usr/share/misc/config.sub
Interestingly, they don't seem to be caught by checkbashisms (maybe I
still have a non working version?)
corsac@hidalgo: checkbashisms /usr/share/*/config.{guess,sub}
possible bashism in /usr/share/automake-1.11/config.guess line 95 (trap with signal numbers):
trap 'exit 1' 1 2 15
possible bashism in /usr/share/automake-1.7/config.guess line 95 (trap with signal numbers):
trap 'exit 1' 1 2 15
possible bashism in /usr/share/misc/config.guess line 95 (trap with signal numbers):
