+"""distutils.emxccompiler
+
+Provides the EMXCCompiler class, a subclass of UnixCCompiler that
+handles the EMX port of the GNU C compiler to OS/2.
+"""
+
+# issues:
+#
+# * OS/2 insists that DLLs can have names no longer than 8 characters
+# We put export_symbols in a def-file, as though the DLL can have
+# an arbitrary length name, but truncate the output filename.
+#
+# * only use OMF objects and use LINK386 as the linker (-Zomf)
+#
+# * always build for multithreading (-Zmt) as the accompanying OS/2 port
+# of Python is only distributed with threads enabled.
+#
+# tested configurations:
+#
+# * EMX gcc 2.81/EMX 0.9d fix03
