On a different side note:
I tried to compile the library using xlclang++ and it resulted in an 
empty (rather malformed) mkerror.h.
I was curious to why and found that the xlclang option '-P' creates a 
.i-file and does not generate the output on stdout.
In case you want to support xlclang, either the option -P needs to be 
dropped or the .i-file put into the following '| grep...'.

Regardless, even xlclang++ runs into the same 'Undefined symbol' after that.

Best regards
