Are header file names case insensitive ?

I'm looking at embedded software application code mostly written in 'C' language.  IAR build tools are used to build this application.  The compiler is EWM16C.  
This embedded application uses Renesas M16C Microcontroller.

One of the header files is:   some_DCA.h

Some 'C' files include   some_DCA.h, whereas, other 'C' files include some_dca.h.   The latter header file doesn't exist.

Will some_DCA.h get included with both spellings?

It depends on the operating system you use. In Windows the file names are case insensitive. In Unix-like system (Linux, RedHat, CentOS, etc) they are case sensitive
