Add .gitignore which ignores autoconf stuff.
Add .gitignore which ignores autoconf stuff.

Note: Assumes you build in a separate object tree.  I.e., does not include Makefile, *.o, etc.  E.g.:

  git clone ... libhtp
  cd libhtp
  autoreconf
  mkdir ../libhtp_obj
  cd ../libhtp_obj
  ../libhtp/configure
  make

If you want to build in your source tree then consider adding local git ignore patterns for build artifacts.
