Just submitted a new version of my CPAN XS module. Something in one of the tools involved in making this module must have changed, because when I 'make' the module I get lots of error messages like the last 2 lines:
cc -c  -I/usr/local/include  -DHAS_FPSETMASK -DHAS_FLOATINGPOINT_H -fn
+o-strict-aliasing -pipe -I/usr/local/include -O2    -DVERSION=\"0.54\
+"  -DXS_VERSION=\"0.54\" -DPIC -fPIC "-I/usr/local/lib/perl5/5.8.9/i3
+86-freebsd/CORE"   MMA.c
MMA.c: In function `boot_IPC__MMA':

Here is what the start of the subject routine looks like:
XS(boot_IPC__MMA)
{
#ifdef dVAR
    dVAR; dXSARGS;
#else
    dXSARGS;
#endif
    char* file = __FILE__;

    PERL_UNUSED_VAR(cv); /* -W */
    PERL_UNUSED_VAR(items); /* -W */
    XS_VERSION_BOOTCHECK ;

    {
        CV * cv ;

        newXS("IPC::MMA::constant", XS_IPC__MMA_constant, file);
        newXS("IPC::MMA::mm_create", XS_IPC__MMA_mm_create, file);

I think these are due to the tools because I go back to my previous version and get the same messages, which didn't used to happen. In fact, the lines above are from my previous version.

Has anyone seen such warnings before? How do I get rid of them? They are likely to alarm potential users.
