+# This file is included by all the other makefiles, thus changes

+# The MINGW32 and MINGW32VERSION variables are preconfigured for
+# MinGW gcc version 3.x and must both be changed for any version
+# earlier than 3.0 or for cygwin. Editing this file is one way to
+# change them. An easier way, at least with GNU make, is to override
+# them on the command line, e.g.
+#   make MINGW32=0 MINGW32VERSION=2.8 -f makefile.g95
+
+# If using Mingw32 (any version), set this to 1.
+# If using Cygwin (any version), set this to 0.
+#
+# This agrees with the instructions given in docs/msw/install.txt .
+# Earlier versions of this makefile suggested setting MINGW32=1 for
+# recent versions of cygwin, but that would give the wrong dll entry
+# point in src/msw/makefile.g95 .
+#
+# With cygwin, there are still some problems compiling wxWindows
+# this way; './configure && make' may work better.
+#
+MINGW32=1
+
+# set MIN_SUFFIX to nothing if you use only MinGW compiler, set it to
+# something MinGW-specific if you want to build wxWindows with more than one
+# compiler

+# Set to your gcc version. Generally 'gcc --version' tells you
+# which version you have. But it cannot distinguish between
+# 2.95.2-1 and earlier suffix versions of 2.95 . In that case,
+# inspect the dates of bin/gcc.exe and bin/ld.exe ; if they
+# are at least
+#   2000-01-21 for gcc.exe and
+#   2000-02-04 for ld.exe
+# then use '2.95-late'.
 #
-# An alternative to editing this file is to create a shell script
-# to export specific variables, and call make with the -e switch
-# to override makefile variables. See wx/install/install.txt.
-# And you can override specific variables on the make command line, e.g.
+# gcc 2.8.x and earlier require struct-return workaround
+#MINGW32VERSION=2.8
 #
-# make -f makefile.unix DEBUG=''
+# gcc 2.95.2 and earlier requires special thunk option
+#MINGW32VERSION=2.9-early
 #
-# You may prefer to use the GNU configure script than raw makefiles -
-# see contrib/wxshlib.
+# mingw gcc-2.95.2-1 supports '-shared'
+# windres provided with gcc-2.95.2-1 supports temp file option
+#MINGW32VERSION=2.95-late
