[ID 20010814.005] Issues with perl 5.6.1 and h2ph
Message ID:

First, let me mention - this isn't a problem with normal apps using perl. It's
only a problem for people still using old perl4 backwards compatible code 
such as sys/socket.ph and friends.

I've got a couple of systems (solaris 2.6, 2.7 based, and redhat 6.2,7.1 based)
that have issues with the generated .ph files.

First problem - it is including defines like 

	...defined(&-Acpu)...

in _h2ph_pre.ph. Those I was able to deal with by the following h2ph change:

+	    next if ($_ =~ /^\-/);
 
             if ($define{$_} =~ /^\d+$/) {
                 print PREAMBLE


but there are lots of other problems as well. For example, I get a number of
prototype errors and other weirdnesses.

On solaris 26:
	Prototype mismatch: sub main::_LARGEFILE_SOURCE vs () at (eval 4) line 1.

On redhat 62:
	Prototype mismatch: sub main::__need_size_t vs () at (eval 50) line 1.
String found where operator expected at (eval 231) line 1, near "&__const 'struct sockaddr'"
        (Missing operator before  'struct sockaddr'?)


Is the h2ph stuff no longer supported, or is this an oddball problem somehow
specific to my local installation of perl?

I am building a fresh install of perl 5.6.1 w/ new module builds, so I'm 
game for anything you'd like me to try. Not 5.7 though. :)

Here's my myconfig output from solaris26:
