  New Revision: 64196

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64196

  Log:
    mjit.c: use -Tc flag explicitly
    
    This option makes sure that the argument is C source file.
    Probably this is not needed, but since I'm debugging it, I want to
    exclude any failure possibility for now.

  Modified files:
    trunk/mjit.c
