P5-T3 revised: obtained the real PsyQ 4.4/4.5/4.6 SDK compilers (proprietary,
kept ignored) and ran CC1PSX 4.5 under the ignored wibo Win32 loader. The SDK's
own README and the binary agree: PsyQ 4.5 CC1PSX = egcs-2.91.66 (egcs-1.1.2),
target mips-sony-psx, assembler ASPSX 2.81.
The open decompals/old-gcc gcc-2.91.66-psx produces instruction-identical
output to the real CC1PSX across ~990 instructions in twelve probe files, so no
proprietary compiler is needed for the matching build. Five reconstructed
original functions are byte-identical with -O2 -G0 -mno-split-addresses.
Corrects the earlier gcc-2.7.2-psx selection, which was an artifact of the
invalid -mcpu=3000 spelling. Records the unresolved 0x8005DEF8 reconstruction.
