Summary: Stripping of -W in MakeMaker Scripts Clashes with HP cc Flag

Initial Comment:
Dear Bugfixers,

it took me many grieves and pains to get the Net-SNMP 
sources with the Perl integration installed on HP-UX 
11.00 with the HP Ansi C compiler.

Below you will find output from various system 
commands and Perl invocation to gather my installation 
environment.

Thanks to the tremendous help from your developer 
Johannes Schmidt-Fischer <jsf@InterFace-AG.com> we 
could finally trace the spots where things went terribly 
wrong for someone installing on HP-UX with the HP 
compiler and who has to link against a Perl build from 
the very same compiler.

The big neglect seems to be that your developers seem 
to assume evreyone is using GCC and a Perl build from 
gcc as well.
While the latter is even true for the Perl that HP 
themselves are shipping on their application CDs and 
offer as prebuild SD depot for download, 
I have to live with my Perl build from the CPAN sources 
that I made with HP ANSI C because I needed Perl 
Oracle integration via DBD::Oracle (another long and 
notorious trail of infamous doom stories).

Someone who scripted those MakeMaker files called 
Makefile.PL in the Perl branch of the tarball
introduced some hideous pattern substitution that 
obviusly was meant to strip off the gcc warning flags 
without putting into consideration that other compilers 
might have valid -W switches.
For this I'd like to draw your attention to the HP-UX 
manpages for cc and ld:

http://docs.hp.com/en/B2355-90680/cc_bundled.1.html

http://docs.hp.com/en/B2355-90680/ld.1.html

What I'm talking of are these substitutions:

[root@terra:/usr/local/tmp/net-snmp-5.2.1]
# find . -type f -name Makefile.PL.orig|xargs grep -
E '\$Params\{'\''?CCFLAGS'\''?}[[:space:]]*=~' 
./perl/default_store/Makefile.PL.orig:  $Params
{'CCFLAGS'} =~ s/ -W[-\w]+//g; # ignore developer 
warning
s
./perl/TrapReceiver/Makefile.PL.orig:   $Params
{'CCFLAGS'} =~ s/ -W[-\w]+//g; # ignore developer 
warning
s
./perl/ASN/Makefile.PL.orig:      $Params{'CCFLAGS'} 
=~ s/ -W[-\w]+//g; # ignore developer warnings
./perl/agent/default_store/Makefile.PL.orig:    $Params
{'CCFLAGS'} =~ s/ -W[-\w]+//g; # ignore developer
 warnings
./perl/agent/Makefile.PL.orig:  $Params{'CCFLAGS'} =~ 
s/ -W[-\w]+//g; # ignore developer warnings
./perl/OID/Makefile.PL.orig:    $Params{'CCFLAGS'} =~ 
s/ -W[-\w]+//g; # ignore developer warnings
./perl/SNMP/Makefile.PL.orig:   $Params{'CCFLAGS'} 
=~ s/ -W[-\w]+//g; # ignore developer warnings

Please note that in the find above I was referring to 
Makefile.PL.orig files which of course in your tarball are 
the real Makefile.PL files.
These had only been renamed by my patch script that 
you may find attached.

I admit that it is quite rediculous to come up with such a 
script where the fixes should be incorporated in the 
original files in the first place.
But I thought it would make my necessary changes 
more obvoius.

All currently active lines are now much more
selective when discarding -W options.
