Warnings for deprecated #import
-------------------------------
The #import directive, often found in legacy Objective-C code from
the NeXTstep and OpenStep era, is deprecated. You should use #include
instead whenever possible, and even if you use #import, you should
protect all your headers against multiple inclusions. The GCC compiler
automatically emits a warning whenever you use #import. For political
and historical reasons (basically for fear of annoying legacy users),
these warnings are disabled by gnustep-make. But if you are not a
legacy user and/or you want to make sure your Objective-C code is not
using any deprecated feature, you should configure gnustep-make with
-disable-import:
./configure --disable-import
If you are a legacy user, and wonder why #import is deprecated,
please search the web and the GCC and GNUstep mailing list archives -
there are very precise and sound technical reasons.
