My approach to this is to avoid non-standard things -- if I
write a patch which is pretty much standard C then it's the
platform's problem if it mishandles it. If I write a patch
that uses a compiler-specific or OS-specific thing then I
have to also provide the relevant alternatives...so I try
to avoid doing that :-)
