hi folks.
enabling gcc10 on sun2 triggered a build failure that i didn't see locally with MKPAM=no builds. the problem is that libhx509 and ftpd both defined yyval and yyerrflag, and the -fno-common default makes them multiply defined. looking at libxh509, it attempts to rename the yacc symbols but these two are either new or missed, so it seems right that we should add those two here too. the question remaining is really is it worth bumping the libhx509 shlib major to rename these? they're wrong to be linked against other things, so it's already problematic, and i don't know what it means currently for eg, ftpd when it uses these symbols currently. thanks. .mrg.
