Is a quick summary of the diffs useful? Most of them are very simple. 
I think it'd be useful to push up the simple/uncontroversial ones.
At least shrink the diffs, if not to zero, at least cut out a bunch.

Here:

  C:\djgpp\src\gcc\4.31\diffs\source\configure.in.diff  
    not obvious  
    perhaps should not increase support for old -with-headers option?  
    use -sysroot instead?  
    *However*, note that djgpp also doesn't use traditional /usr/include structure, so...?  


  C:\djgpp\src\gcc\4.31\diffs\source\config\gxx-include-dir.m4.diff  
    c++ vs. cxx  
    4.3.1 vs. 4.31 (gcc_version vs. gcc_version_dir)  

  C:\djgpp\src\gcc\4.31\diffs\source\fixincludes\configure.ac.diff  
    4.3.1 vs. 4.31 (gcc_version vs. gcc_version_dir)  

  C:\djgpp\src\gcc\4.31\diffs\source\fixincludes\Makefile.in.diff

  C:\djgpp\src\gcc\4.31\diffs\source\gcc\c-common.c.diff  
    less strict checking regarding builtin functions; why?  

  C:\djgpp\src\gcc\4.31\diffs\source\gcc\c-decl.c.diff  
    less strict checking regarding builtin functions; why?  

  C:\djgpp\src\gcc\4.31\diffs\source\gcc\config.host.diff  
    c++ vs. cxx  
    picking host makefile fragment  

  C:\djgpp\src\gcc\4.31\diffs\source\gcc\configure.ac.diff  
    c++ vs. cxx
