Silent warnings about unsused variables in Makefile.PL probes #117

Closed ppisar closed 1 month ago

ppisar commented 1 month ago

Makefile.PL checks for available functions by assigning their address to a variable. Value of the variable is then never used and GCC warns like this:

/tmp/pmts0000.c: In function ‘main’:
/tmp/pmts0000.c:7:12: warning: unused variable ‘ixi’ [-Wunused-variable]
7 |     void * ixi = strcasecmp;
  |            ^~~

and like this:

/usr/lib64/perl5/CORE/XSUB.h:166:20: warning: unused variable ‘items’ [-Wunused-variable]
  166 | #define dITEMS I32 items = (I32)(SP - MARK)
  |                    ^~~~~
/usr/lib64/perl5/CORE/XSUB.h:169:23: note: in expansion of macro ‘dITEMS’
  169 |         dSP; dAXMARK; dITEMS
  |                       ^~~~~~
/tmp/pmts0000.c:8:4: note: in expansion of macro ‘dXSARGS’
8 |    dXSARGS;
  |    ^~~~~~~

This patch silents the warnings.
