Hi,
When I built qemu on my x86_32 host with following configure line:
$ ./configure --prefix=/usr/local/qemus/master \
--target-list=i386-softmmu
$ make
The build will always fail with message:
----------------------------------------
...
CC i386-softmmu/fpu/softfloat-native.o
/mnt/farm/my_repo/qemu/fpu/softfloat-native.c:130:5: error:
"HOST_LONG_BITS" is not defined
make[1]: *** [fpu/softfloat-native.o] Error 1
make: *** [subdir-i386-softmmu] Error 2
----------------------------------------
Is this a known issue or something wrong with my configure line?
Though I can make it work with a minor nasty patch:
==============
diff --git a/fpu/softfloat-native.c b/fpu/softfloat-native.c
index 049c830..5ba5013 100644

I thought it may necessary to ask if something wrong with above hack.
And can we get the problem fixed properly?
Thanks.
