* go32-nat.c (struct env387): Remove declaration.
(print_387_status, i386_go32_float_info): Remove redundant functions. (regno_mapping, sig_map, excepn_map): Add braces around inner initializers. (many functions): Use ATTRIBUTE_UNUSED to shut up the compiler; fix code which mixed signed with unsigned. (go32_resume): Use TARGET_SIGNAL_LAST instead of -1. (go32_wait): Initialize INT3_addr. (go32_fetch_registers): Extend all FP registers that are shorter than 4 bytes to 32 bits. Support 32 standard FP registers defined on config/i386/tm-i386.h. (store_register): Support 32 FP registers. (go32_create_inferior): Don't crash if handed a NULL pointer instead of exec file name. (ignore): Remove unused function. (go32_insert_hw_breakpoint): Remove unused variables. (init_go32_ops): Set value of processing_gcc_compilation to 2.
