#Note on the -qNOro option

#  The AIX compiler by default allocates memory for string literals in the
#  read only area. As result, CLIP clients crash with segmentation fault 
#  when cdevClientRequestObj cleans up constant message strings passed by
#  the user (in the code below "message" points directly to the user string)
