What steps will reproduce the problem?
1. Install toolchain as described in [HowTo_en] wiki page (prebuilt packages 
for Ubuntu 13.04)
2. Create HelloWorld project from "Build an iOS App" this wiki page section.
3. try to make it

What is the expected output? What do you see instead?

I see:
make
ios-clang -c -I/usr/include/llvm-c-3.2 -objc-arc -fblocks -g0 -O2 -I"." 
HelloWorldApplication.m -o HelloWorldApplication.o

What version of the product are you using? On what operating system?

Ubuntu 13.04 with prebuild packages provided in download section.

Please provide any additional information below.

stdarg.h present in iPhoneOS5.0.sdk/usr/include/c++/4.2.1/tr1 folder, but it 
also includes other stdarg.h from somewhere?
Same error using 6.0 SDK.

Hi! solved this problem by exporting flags:

export CXXFLAGS=-I/usr/include/clang/3.2/include
export CFLAGS=-I/usr/include/clang/3.2/include

Don't do this, it's dangerous and may break Makefiles, configure scripts and so 
on.
Better use the C_INCLUDE_PATH and CPLUS_INCLUDE_PATH environment variables.

export C_INCLUDE_PATH="path_to_float.h:$C_INCLUDE_PATH"
export CPLUS_INCLUDE_PATH="path_to_float.h:$CPLUS_INCLUDE_PATH"

Put this into your ~/.profile .
