# FreeBSD standard (shared) ELF startup code for Free Pascal
#
# FreeBSD RunTime dynamic loader only
# calls the functions specified by -init
# as functions without parameters
# Thus, it is not possible to retrieve argc, argv and envp
# for libraries.
# On x86_64 CPU, using weak for the operatingsystem_parameter_XXX
# allows to bind to main program parameters,
# but this does not seem to work for i386 loader.
