Hello, Tech-Talkers.

On Darwin, with EPICS Base 3.14.12.4, I'd like to create and install a C
header file that has some @VAR@ macros expanded using the INC, EXPAND,
and EXPAND_VARS build system variables as described in the EPICS Base
3.14 release notes, but the build fails with the following error:

===
make[3]: *** No rule to make target `../O.Common/favorites.h', needed by `inc'.  Stop.
===

Here's how to reproduce the problem:

1. $ mkdir example

2. $ cd example

3. $ makeBaseApp.pl -t example example

4. Create the file exampleApp/src/favorites.h@ containing the line:

     #define FAVCOLOR @FAVCOLOR@

5. Add the lines

     EXPAND_VARS += FAVCOLOR=red
     EXPAND += favorites.h@
     INC += favorites.h

   below the line "#  ADD MACRO DEFINITIONS AFTER THIS LINE" in
   exampleApp/src/Makefile:

   $ vi exampleApp/src/Makefile

6. make

This produces the following output:

===
/Applications/Xcode.app/Contents/Developer/usr/bin/make -C ./configure install 
perl /opt/epics-3.14.12.4/bin/darwin-x86/makeMakefile.pl O.darwin-x86 ../..

make[2]: *** [install.darwin-x86] Error 2

make: *** [exampleApp.install] Error 2

Am I doing something wrong, or is this broken?

I can achieve what I want by renaming favorites.h@ to favorites.h.in
and writing my own rule with the following four lines in
exampleApp/src/Makefile instead of the three listed above:

  ../O.Common/favorites.h: ../favorites.h.in
  	$(PERL) $(TOOLS)/expandVars.pl -t $(INSTALL_LOCATION) \
  	    -D FAVCOLOR=red $< $@
  INC += favorites.h

But it would be nice if I didn't need to do this.

Environment:
* Processor: 2.3 GHz Intel Core i7 (4 cores)
* Memory: 8 GB
* OS: Mac OS X 10.10.1
* EPICS Base 3.14.12.4 + Known Problems patches up to 2014-04-07
  Architecture: darwin-x86
  Architecture Class: x86_64

Thank you!
