Test handling of -I.
|
|
|
|
Multiple C<-I> switches are supposed to
|
|
prepend left-to-right:
|
|
|
|
-Ifoo -Ibar
|
|
|
|
should make C<@*INC> look like:
|
|
|
|
foo
|
|
bar
|
|
...
|
|
|
|
Duplication of directories on the command line is mirrored
|
|
in the C<@*INC> variable, so C<pugs -Ilib -Ilib> will have B<two>
|
|
entries C<lib/> in C<@*INC>.
