I am trying to compile GCC-2.95 in MinGW environment but its not
    Compiling. I am gating some error at the time of compiling Bunitils-2.10.1.
    But using the same source file (Bunitils-2.10.1, GCC-2.95, newlib-1.12.0)
    I am able to compile GCC in Cygwin and Linux environment for target
    arm-elf  and its generating all the exe file but the problem is there we have
    to use Cygwin means one dependence is there.
    Is it possible to compile GCC for target arm-elf which wouldnt use Cygwin?
    Dll and I can run it in MS-DOS environment without having any dependences.
    Below I am mentioning all the details which I have done to solve the problem
      Bison 1.35
