Comment:

 Attached patch fixes that. It basically enhances deriveConstants utility
 to also support Solaris' nm program.
 Christian please test it. I've tested it here on Solaris 11.1 and Solaris
 10 update 8. I'm using PATH which is set to Single Unix Specification 3
 standard, that means nm is taken from /usr/xpg4/bin directory
