Subject: [PATCH] Update Windows build flags

/MP2 limits the build processes to a maximum of 2. Many CPU's nowadays have more than two cores, so the integer specifier is removed so that the build is not artificially constrained to two cores.

/FS allows multiple compiler processes to write to the .pdb file; it should be used in conjunction with /MP to speed up the build.

/permissive- disables certain MSVC-specific extensions and follows the C standard more closely. Using this flag should help to ensure behavior matches gcc & clang a little more closely.

Note, /utf-8 does NOT build the program with Unicode support. It merely indicates to the compiler that the source files are using UTF-8 encoding.
