But in my situation they compile. And, since I'm using STLport's
iostreams, I expected the macro _STLP_OWN_IOSTREAMS to be defined.

I have checked the STLport docs and it seems that the "official" macro
is _STLP_NO_OWN_IOSTREAMS (with the "no" inside), not
_STLP_OWN_IOSTREAMS. Of course one would expect that when either is
defined the other isn't, but in my case they are both undefined. I
don't know if this intentional or a problem in the STLport code.

Anyhow, considering that only _STLP_NO_OWN_IOSTREAMS is clearly
documented, isn't just that the above code from config/suffix.hpp
should be written as:

#if defined(_STLP_NO_OWN_IOSTREAMS)    // <---
 && defined(_STLP_USE_NAMESPACES) &&
defined(BOOST_NO_USING_TEMPLATE) && !defined(__BORLANDC__)
#  define BOOST_NO_STD_LOCALE
#endif

?
