gcc warning: unused variable 'ix'

[atoomic]

notice these warnings from this build log http://perl.develop-help.com/raw/?id=223899

Compiler messages(gcc):
Encode.c:1356:5: warning: unused variable 'ix' [-Wunused-variable]
../../XSUB.h:185:20: note: expanded from macro 'dXSI32'
Encode.c:1398:5: warning: unused variable 'ix' [-Wunused-variable]
./const-xs.inc:128:42: warning: AI_IDN_ALLOW_UNASSIGNED is deprecated [-W#pragma-messages]

this is coming from dXSI32
for example in XS_EUPXS I'm not even sure it's required

[atoomic]

I see this is coming from the .c file generated from .xs one... where we are using aliases in XS function without having a different code for it, thus no need to use ix variable

for example in decode, the alias is just there as an alternate to decode and do not alter the code

 SV *
 decode(encoding, octets, check = NULL)
 SV *    encoding
 SV *    octets
 SV *    check
 ALIAS:
     bytes2str = 0

Looks like we cannot define XS alias without having dXSI32 loaded...

closing this case as there is nothing we can do there

so looks like something for xsubpp... you can report issue to it.

[atoomic]

going to report it, this is a convenient feature more than anything else
