A number of autogenerated header files are not added to ".gitignore" in "$source_base".
For example, in a current project of mine, $ git status shows lib/alloca.h lib/fcntl.h lib/inttypes.h lib/langinfo.h lib/limits.h lib/locale.h lib/signal.h lib/stdio.h lib/stdlib.h lib/string.h lib/sys/ lib/time.h lib/unistd.h lib/wchar.h lib/wctype.h Currently, Gnulib only adds "in"-files like "alloca.h.in" to ".gitignore".
