GCC 4.4.0 patch 1.7

Changes this version:

Libgcc now built for TMS9900
Implemented optimized assembly functions in libgcc for:
  count leading zero bits
  count trailing zero bits
  find index of least significant set bit
  count set bits
  calculate parity bit
  signed and unsigned 32-bit division and modulus
Fixed 32-bit multiplies, was only doing unsigned multiply
Fixed 32-bit negation, was emitting invalid NEG instruction
Removed fake PC register (Yay!)
New build instructions to make libgcc
Fixed function prologue and epilogue, was saving R11 unnecessarily
Optimized function epilogue, saving a few cycles
Enforced correct use of R11 register, was causing randomly broken code

Binutils 2.19.1 patch 1.4

Changes this version:

Fixed bug prohibiting the use of single quotes in a string Strings my be in either TI-style 'stuff' or C-style "stuff" TI-style strings follow E/A text rules C-style strings may include standard escape codes "example\n"

Reduced overhead needed for multiply instructions
Fixed bug causing structres to be loaded into registers
Structures used as function arguments now passed by reference
Fixed more bugs causing bad int-to-char conversions
