autoconf: library version comparsion fails

[Gavriel Fleischer]

Package: autoconf
Version: 2.61-4
Severity: important

*** Please type your report below this line ***

When autoconf generates a configure script, the following line is translated
wrong:
GP_CHECK_LIBRARY([LIBGPHOTO2], [libgphoto2], [>= 2.3.1.3.trunk])


When I have libgphoto 2.4.0 installed, and 2.3.1.3.trunk or greater is
required, the code fails to check, because of the
following:

_tmp=false
if   test "2" "-lt" "2"; then _tmp=true;    # false
elif test "4" "-lt" "3"; then _tmp=true;    # false
elif test "0" "-lt" "1"; then _tmp=true;    # TRUE!
elif test "x" = "x" && test "x.3.trunk" != "x"; then _tmp=true;
elif test "" "-lt" ".3.trunk"; then _tmp=true;
fi

Although 2.4 > 2.3, 0 < 1, and the comparsion fails.


The translation of
GP_CHECK_LIBRARY([LIBGPHOTO2], [libgphoto2], [>= 2.3.1.3.trunk])
is this:
