This is a bug report for perl from tcallawa@​redhat.com,
generated with the help of perlbug 1.35 running under perl v5.8.8.

As part of the review process for Perl, I'm opening bugs for the
long list of patches to perl that Fedora has been carrying around
(in some cases, for years), in the hopes that these fixes can be
applied upstream. Unfortunately, I am not the original author of
these patches, so please be patient with me as I attempt to
describe why Fedora uses them.

Linux supports a wide range of architectures, and while most of them
are ok with -fpic, some of them (e.g. SPARC) need -fPIC. To be safe,
Linux should default to -fPIC.

I'm glad to see these being added like this.
I'm unable to apply these for the next 10 days, so please
be patient, and if I forget, remind me

Linux supports a wide range of architectures, and while most of them

Linux should default to -fPIC.

I /think/ I agree. Please comment from people who know more
about the implications

Thank you for doing this. This sort of feedback from large and diverse
user communities is very helpful.

Linux supports a wide range of architectures, and while most of them
are ok with -fpic, some of them (e.g. SPARC) need -fPIC. To be safe,
Linux should default to -fPIC.

That sounds like a good plan. I haven't tested it for years, but a long
time ago I did find a measurable difference between -fpic and -fPIC.
However, the safer default of -fPIC makes sense. If anyone would care to
test -fpic for a particular architecture and override the default for that
particular architecture, that would be fine too, but as you say, the safer
choice should be the default.
