In zipOpenNewFileInZip4_64:
1206 │ #ifdef HAVE_BZIP2
1207 │ if ((err==ZIP_OK) && (zi->ci.method == Z_DEFLATED || zi->ci.method
== Z_BZIP2ED) && (!zi->ci.raw))
1208 │ #else
1209 │ if ((err==ZIP_OK) && (zi->ci.method == Z_DEFLATED) &&
(!zi->ci.raw))
1210 │ #endif
1211 │ {
1212 │ if(zi->ci.method == Z_DEFLATED)
1213 │ {
Arguably a false positive: it's going to be a repeated test if the preprocessor
uses line 1209, but not if it uses line 1207.
