Updated gcc-ia16 for DOS
TK Chia has been working to port the GNU C Compiler to DOS, using the ia16 instruction set. That means you can use the GNU C compiler to make 16-bit DOS programs (previously, if you wanted to use GNU C, you used the DJGPP port, but the compiled DOS programs required a 32-bit CPU; this compilers programs that run on 16-bit.) TK Chia recently uploaded a new, updated package set for the gcc-ia16 toolchain at Github. Features in this updated gcc-ia16 toolchain include: * fixes a number of bugs which was causing the compiler to produce incorrect or suboptimal code (thanks to Bart Oldeman) * adds a new experimental function calling convention, regparmcall * adds a number of features to the GCC internal runtime library (libgcc) and the C runtime library (newlib) to better detect and report program logic errors, especially memory corruption errors.
