Yes; either look in lang-specs.h in the language frontend subdirectory
or, for C, look for the default_compilers structure in gcc/gcc.c. For
example, after:

  /* Next come the entries for C.  */
  {".c", "@c", 0},

add the line

  {".mip", "@c", 0},

Better, though, unless you have a lot of .mip files, would be to specify
the language on the command line per compile:

    gcc -x c -c test.mip
