By default building GCC does not regenerate, e.g., "configure" from 
"configure.ac" or the files under libgfortran/generated/ from 
libgfortran/m4 -- even if they changed. Only if you build with 
--enable-maintainer-mode, GCC does.

The general GCC policy is to post only the patch itself and exclude the 
generated files to make reviewing easier. For gfortran patches, they 
were often included on the basis that many users tests the patches (as 
this thread shows) and as --enable-maintainer-mode requires very 
specific versions of the autotools, which are usually not installed. For 
GCC patches, reviewers will complain if you include the generated files; 
a reviewer typically also does not apply and test a patch but only looks 
at the patch. Thus, including the generated files just makes the review 
process harder.
