23 /* Declare the variable flag_half_pic as 'int' instead of 'extern
24 int', so that BSS variables are created (even though this is not
25 strict ANSI). This is because rtl.c now refers to the
26 CONSTANT_ADDRESS_P macro, which in turn refers to flag_half_pic,
27 and wants to call half_pic_address_p, whose address we also store
28 in a BSS variable. This way, the gen* programs won't get
29 unknown symbol errors when being linked (flag_half_pic will never
30 be true in the gen* programs). */
