# Linkers on different platforms need different options to
# specify that directories need to be added to the list of
# directories searched for dependencies when a dynamic library
# is sought. GCC has to be told to pass the -R option through
# to the linker, whereas other compilers just know this.
# Other compilers may need something slightly different. At
# this time, there's no way to determine this information from
# the configuration data stored in the Python installation, so
# we use this hack.
