GCC -include option and waf

[Sebastian Huber]

Hello,

how can I use the "-include file" GCC option with waf? In case I use this:

+    bld.objects(target = "objs07",
+                features = "c",
+                cflags = ['-include 
freebsd/sys/contrib/ncsw/build/dflags.h'] + cflags,

I get:

Waf: Entering directory 
`/scratch/git-rtems-libbsd/build/powerpc-rtems4.12-qoriq_t4240rdb'
[351/896] c: freebsd/sys/contrib/ncsw/Peripherals/BM/bm.c ->

'-std=gnu++11', '-include freebsd/sys/contrib/ncsw/build/dflags.h', ..., 
'../../freebsd/sys/contrib/ncsw/Peripherals/BM/bm.c', '-c', '-o', 
'freebsd/sys/contrib/ncsw/Peripherals/BM/bm.c.16.o']

E.g. what is the equivalent of $(top_srcdir) or $(srcdir) in waf?

This -include is something else than a simple -I. It instructs GCC to 
include the specified file. So, this is a command line #include <...>.
