In blead (and possibly elsewhere), Normalize.xs emits a compiler warning
due the 'ix' var, which is made available for XS subs that declare aliases:
In file included from Normalize.xs:14:0:
Normalize.c: In function ‘XS_Unicode__Normalize_isComp2nd’:
../../XSUB.h:202:20: warning: unused variable ‘ix’ [-Wunused-variable]
#define dXSI32 I32 ix = XSANY.any_i32
^
Normalize.c:1104:5: note: in expansion of macro ‘dXSI32’
dXSI32;
^
The following diff seems to fix it:

My Dad used to say 'always fight fire with fire', which is probably why
he got thrown out of the fire brigade.
