add sourcefiles to gcc

[nico]

Hi,

if I want to add some source to the gcc, what do I have to do?

I think the source files have to be in the gcc-subdirectory. Then I  
have to change the Makefile.in in the same directory ( I didn't found  
any hint that this file is generated by autogen or automake - so I  
think it has to be changed manually).

Do I forget something?

Best regards, NM
