In the build options it is possible under miscellaneous to specify a file that contains options. In CCSv10.4 specifying a file will result in an error at the top of the dialog saying that it is not able to find the file.

Cannot open command file "name and path" : No such file or directory

The build actually works fine as it can find the file. This did not occur in CCSv9.2.

Specifying the options using the CDT settings under Advanced -> C/C++ Build works fine.
