+# 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.
