Unportable test(1) operator
In configure.in there are two unportable uses of "==" as a test(1) comparison operator. POSIX mandates "=", only bash supports "==".
In configure.in, it's this line:
if test "$host_cpu" == "i386" -o "$host_cpu" == "x86_64"; then
(two occurrences)
In Makefile.am, this line:
@if [[ "$(PREV)" == "" ]]; then
could be made non-bash specific by using single '[', '=', and ']' instead of double ones.
Please fix these. Thank you!
