 are bound at link-time and one in which symbols are bound at runtime only,
 similar to ELF@.  In case of doubt use @code{LDFLAGS=-Wl,-brtl} for the latter style.

+On AIX, native tools are to be preferred over binutils; especially for C++ code,

 For C++ code with templates, it may be necessary to specify the way the compiler
 will generate the instantiations.  For Portland pgCC version5, use
