When I do this with GCC, the .deps/<filename> also contains a line

main.h:

and I have no problem removing main.h and the #include and just run 
'make'. If you don't have that line (main.h:), it's bug in your compiler 
and I suggest you report it.

As a rule of thumb 'make clean' does not remove things that were created 
during configure (or upstream), but obviously depends on how people 
write the Makefile.am.
