Test Perl version 5.003 - 5.005 on Travis

[pali]

Documentation says ppport.h supports Perl versions from 5.003, but on Travis is configured minimal version 5.6.0.

suggestion, if we can confirm that it s not passing with versions below 5.6.0 maybe we should change the wording there... as I think during our last discussion we were targeting 5.6.0
@khwilliamson do you we should provide support below 5.6.0 ?

[pali]

5.5.3 is passing

[pali]

Anyway, I did some modification to perlbrew and travis-perl-helpers and seems that it allows me to add also older perl versions to Travis... I will try to create a pull request in next days.

Support for 5.005_01 - 5.005_05 into travis-perl-helpers is in this pull request:
travis-perl/helpers#72

5.005 cannot be compiled with current patchperl, compilation fails on error:
https://travis-ci.org/pali/travis-perl-helpers/jobs/545867885

Where is your C library?

do you we should provide support below 5.6.0?

How many distributions are on cpan that use ppport.h that don't have a minimum of 5.6? I'm guessing very few.

If pali can provide patches before 5.6, I think it's fine to push them. But I don't think we need to "support" earlier than really 5.8.
