#
# Module:  makedeps.sh
# Author:  Toni <matzeton@googlemail.com>
# Purpose: Build full host- and mingw64 C toolchain without multilib support ..
#          (Using built-in specs.)
# Changed: 04.01.2018
#
# Automated Build Steps:
#   1. build host binutils
#   2. build host gcc
#   3. build host python
#   4. build host tor (try)
#   5. build mingw64 binutils
#   6. build mingw64 gcc core (with mingw64 headers)
#   7. build mingw64 winpthreads
#   8. build mingw64 gcc
#   9. build mingw tor/libtor and dependencies (try)
#
# mingw64 target      : i686-w64-mingw32
# mingw64 Thread model: WINPTHREAD
