I'm using Eclipse CDT ( helios ). 开发者_JS百科The syntax highlighting is missing When I open some , and not all, *.h files in a project. and Sometimes the syntax highlighting is activated and navigation using hyperlinks isn't activated.

I can't even use ( shift + ctrl + T ) to navigate to other elements when the Editor is on some of the *.h files.

The same exact thing happens for *.S files.

edit

Everything ( syntax highlighting, hyperlinks, and shift+ctrl+T ) is working correctly with *.cpp files.

Make sure that CDT isn't configured to abort syntax highlighting in big files (see CDT configuration). It is enabled by default...
