From prj@po.cwru.edu

This is a bug report for perl from prj@​multivac.cwru.edu,
generated with the help of perlbug 1.33 running under perl v5.6.1.

---

I installed perl 5.6.1, and my Config.pm has​:
ccsymbols='-Acpu=i386 -Amachine=i386 -Asystem=posix [...snip...]'

This causes h2ph to emit these in _h2ph_pre.ph​:
unless (defined &-Acpu) { sub -Acpu() { &i386 } }

unless (defined &-Amachine) { sub -Amachine() { &i386 } }

unless (defined &-Asystem) { sub -Asystem() { &posix } }

But perl chokes on these​:
Warning​: Use of "defined" without parens is ambiguous at /package/host/localhost/perl-5.6.1-2/lib/site_perl/5.6.1/i686-linux-64int-ld/_h2ph_pre.ph line 2.
Bareword found where operator expected at /package/host/localhost/perl-5.6.1-2/lib/site_perl/5.6.1/i686-linux-64int-ld/_h2ph_pre.ph line 2, near "&-Acpu"
  (Missing operator before Acpu?)
syntax error at /package/host/localhost/perl-5.6.1-2/lib/site_perl/5.6.1/i686-linux-64int-ld/_h2ph_pre.ph line 2, near "&-Acpu"

Is it right for $Config{ccsymbols} to include -A*? Is it right for
h2ph to include them? Will parentheses fix this, or should they be
removed entirely? Any ideas on how they got into ccsymbols, and how I
can prevent that the next time I install perl?

This ticket was filed more than 11 years ago, but, AFAICT, it has never
received a reply.

Is there anyone familiar with '-A' in ccsymbols and with h2ph who could
take a crack at a response?

Thank you very much.
