Sublime Text 3 cannot support nesC language Syntax Highlighting

[dayDPTR]

I installed Sublime Text 3 editor in Window10 OS, and then got and installed this package(nesC.tmbundle), by using Package Control, it only supports C language syntax highlighting, cannot support nesC‘s own syntax highlighting.
I tried to comment the code from Line 16 to Line 19 in nesC.tmLanguage from the Syntax directory , and then the nesC's own syntax highlighting can be supported, but the C language syntax highlighting cannot be supported.
could you help track and fix this issue?
