> When building xerces-c 3.2.4, it detects some system headers during the c=
onfiguration step and then defines symbols if these are headers are found.
> If the headers are not found, the symbols are just not defined (instead o=
f being defined to the value zero).
> However, the installed header files (that other projects use) check these=
 symbols with `#if` instead of `#ifdef`, which doesn't work well with undef=
ined symbols.
> =C2=A0
> I've attached a patch switching which fixes the problem for me.
