NAG FL InterfaceThread Unsafe Routines

Most routines in the NAG Library are thread safe, however there are some routines that are not thread safe as they use global variables (such as module variables, common blocks or variables with the SAVE attribute). See Section 1 in FL Interface Multithreading for further information.
