Actually, #ifndef HAVE_LD_NO_DOT_SYMS behaves exactly the same as
#if DOT_SYMBOLS here. The following
#define DOT_SYMBOLS dot_symbols
#if DOT_SYMBOLS
use_dot_symbol_version
#else
do_not_use_dot_symbol_version
#endif
will result in do_not_use_dot_symbol_version. Admittedly, relying on
this particular C pre-processor behaviour doesn't make the code very
clear.
