How to run solaris binary file

If a process uses localtime or similar time functions which use "struct tm", you sould set an environment variable SOLARIS_COMPAT wich some value (the value does not matter).

Example of Communigate Pro:

server# SOLARIS_COMPAT=yes /opt/CommuniGate/CGServer --Base /var/CommuniGate --Daemon
