Problem is, these symbols are compiler specific. It is definitely
__unix__ for gcc, but all __<foo> symbols are reserved for the
implementation (i.e. platform specific).

Hmm. Those still seem wrong.  I'm guessing what is wanted is:

 foo = "Some line of text.\n"\
 "\tAnother line of text with a leading tab character.\n";

Quotes should not be broken across lines.  It is not the right way to
embed newlines (this isn't Perl or sh ...) since the compiler will
probably strip those newlines when parsing the code.

There're still some instances of snprintf()...
