# FIXME:
#
# The -fno-optimize-sibling-calls should be removed as soon as a bug
# in GCC concerning the "large" memory model and tail call optimization
# is fixed.
#
# When GCC generates a code for tail call, instead of generating ..
#
#   jmp *fnc
#
# it generates an assembly code with an illegal immediate prefix:
#
#   jmp *$fnc
#
# See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48385 for reference.
