When I tried to build Win32::SecretFile I got the following errors:

Which confuses me because in the exact same environment and using the same includes I build my code without errors:

I have a work around that fixes the unresolved externals (but not the 'ConvertSidToStringSid' undefined; assuming extern returning int?); and that is to explicitly use the A versions of the two functions:

            if (ConvertSidToStringSidA(sid, &sid_as_string)) {
                PSECURITY_DESCRIPTOR sd = NULL;
                DWORD sd_size;
                SV *ssd_as_sv = sv_2mortal(newSVpvf(ssd_template, sid_
+as_string, sid_as_string));
                LocalFree(sid_as_string);
                if (ConvertStringSecurityDescriptorToSecurityDescripto
+rA(SvPV_nolen(ssd_as_sv),
                                                                      
+  SDDL_REVISION_1,
                                                                      
+  &sd, &sd_size)) {

The the build completes:
