ability to specify a type of the input file with the -x switch

    Usage example: tcc -xc ex5.cgi
    From a gcc docs:

    You can specify the input language explicitly with the -x option:

    -x language
    Specify explicitly the language for the following input files
    (rather than letting the compiler choose a default based on the file
    name suffix). This option applies to all following input files until
    the next -x option. Possible values for language are:

        c  c-header  c-cpp-output
        c++  c++-header  c++-cpp-output
        objective-c  objective-c-header  objective-c-cpp-output
        objective-c++ objective-c++-header objective-c++-cpp-output
        assembler  assembler-with-cpp
        ada
        f77  f77-cpp-input f95  f95-cpp-input
        java

    -x none
    Turn off any specification of a language, so that subsequent files
    are handled according to their file name suffixes (as they are if -x
    has not been used at all)
