   4 # This file is included by all the other makefiles, thus changes
   5 # made here take effect everywhere (except where overriden).
   6 # The settings are for GnuWin32-derived compilers, i.e. Cygwin and Mingw32.

  13 # The MINGW32 and MINGW32VERSION variables are preconfigured for
  14 # MinGW gcc version 3.x and must both be changed for any version
  15 # earlier than 3.0 or for cygwin. Editing this file is one way to
  16 # change them. An easier way, at least with GNU make, is to override
  17 # them on the command line, e.g.
  18 #   make MINGW32=0 MINGW32VERSION=2.8 -f makefile.g95
  19
  20 # If using Mingw32 (any version), set this to 1.
  21 # If using Cygwin (any version), set this to 0.
  22 #
  23 # This agrees with the instructions given in docs/msw/install.txt .
  24 # Earlier versions of this makefile suggested setting MINGW32=1 for
  25 # recent versions of cygwin, but that would give the wrong dll entry
  26 # point in src/msw/makefile.g95 .
  27 #

  29 # this way; './configure && make' may work better.

  34 # which version you have. But it cannot distinguish between
  35 # 2.95.2-1 and earlier suffix versions of 2.95 . In that case,
  36 # inspect the dates of bin/gcc.exe and bin/ld.exe ; if they
  37 # are at least
  38 #   2000-01-21 for gcc.exe and
  39 #   2000-02-04 for ld.exe
  40 # then use '2.95-late'.
