      This problem only occurs on Windows.

      The file stub.c is a complete one line program.  The file options.txt has these lines ...

      stub.c
-o stub.out
-Wl,-c
-L"C:/d12345689012345678901234567890123456789012345678901234567890123456789/that/does/not/exist"
-L"C:/d12345689012345678901234567890123456789012345678901234567890123456789/that/does/not/exist"
-L"C:/d12345689012345678901234567890123456789012345678901234567890123456789/that/does/not/exist"
<... repeated many more times ...>

      The number of characters in options.txt is around 39,400.

       Build it ...

      % tiarmclang @options.txt
tiarmclang: error: unable to execute command: Couldn't execute program 'C:\ti\compilers\ti-cgt-armllvm_3.2.2.LTS\bin\tiarmlnk.exe': The filename or extension is too long.  (0xCE)
tiarmclang: error: tiarmlnk command failed with exit code 1 (use -v to see invocation)

      Build it again with -v to see the command tiarmclang constructs for the invocation of tiarmlnk. It is very long, and Windows rejects it.
