manujose 0:3667ad9a98cc 43 * Implementation of local continuations based on the "Labels as

manujose 0:3667ad9a98cc 47 *
manujose 0:3667ad9a98cc 48 * This implementation of local continuations is based on a special
manujose 0:3667ad9a98cc 49 * feature of the GCC C compiler called "labels as values". This
manujose 0:3667ad9a98cc 50 * feature allows assigning pointers with the address of the code
manujose 0:3667ad9a98cc 51 * corresponding to a particular C label.
manujose 0:3667ad9a98cc 52 *
manujose 0:3667ad9a98cc 53 * For more information, see the GCC documentation:
manujose 0:3667ad9a98cc 54 * http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html
