Hi Dmitry,

Please squash this patch into the previous one, and send a single fixed patch.

A couple more comments below.

Since you don't use Buildroot's autoconf support, this comment is no longer 
relevant.

You can used $(TARGET_CONFIGURE_OPTS) here as well.

Well, I thought this would be the explanation why there is a configure
script, yet it is a GENTARGET.

I tried that, and it did not compile. -D__i386__ should be given
explicitly to cc.

Thanks.

The comment needs to be reworded, then. Something like: "v86d's configure 
script is not autoconf-based, so we use GENTARGET".

Ah, you're right. I haven't noticed the quotes delimiting the CC variable.

This -D is rather a CFLAGS, so:

	$(MAKE) $(TARGET_CONFIGURE_OPTS) CFLAGS="$(TARGET_CFLAGS) -D__i386__" -C $(@D) all

But then you'll have CFLAGS defined twice. Is this OK?

You'll have a first definition of CFLAGS in TARGET_CONFIGURE_OPTS,
overriden by the local redefinition. We do this in numerous places in
Buildroot already.

Is this make behaviour documented? I couldn't find any mention of this in the 
manual.

No, it does not work this way. Value of $(CC) with -D__i386__ should
be passed deeper down to the lowest level Makefile in order for v86d
to compile.

/40G2/golubovsky/src/buildroot-patching/buildroot/output/host/usr/bin/i586-unknown-linux-uclibc-gcc
-D__i386__ -c -pipe -Os  -o fpu.o fpu.c
In file included from decode.c:41:0:
x86emu/x86emui.h:64:20: fatal error: x86emu.h: No such file or directory

(the way you proposed) does not work as local flags are lost.

But:

/40G2/golubovsky/src/buildroot-patching/buildroot/output/host/usr/bin/i586-unknown-linux-uclibc-gcc
-D__i386__ -c -I. -I../../include -I../../include/x86emu -o decode.o
decode.c
v86_x86emu.c: In function 'v86_init':
v86_x86emu.c:50:3: warning: initialization from incompatible pointer type
v86_x86emu.c:53:3: warning: initialization from incompatible pointer type
v86_x86emu.c:57:3: warning: initialization from incompatible pointer type
v86_x86emu.c:58:3: warning: initialization from incompatible pointer type
v86_x86emu.c:59:3: warning: initialization from incompatible pointer type

v86_x86emu.c:61:3: warning: initialization from incompatible pointer type
v86_x86emu.c:62:3: warning: initialization from incompatible pointer type

(my way) works as it is only $CC that is needed by the lower level Makefile.

I'll make other changes as recommended.

Thanks.
