Getting a pointer to the PEB in C, for every architecture that NT was ported to (where at least one build of the port was leaked/released)
// Gets a pointer to the PEB for x86, x64, ARM, ARM64, IA64, Alpha AXP, MIPS, and PowerPC.
// This relies on MS-compiler intrinsics.
// It has only been tested on x86/x64/ARMv7.

return (PEB*)(__readgsqword(0x60));
#elif _M_IX86

#elif _M_ARM
