Interesting.  When I type the command as you provided it (using cut-and-paste) I get:


hendrik at lovesong:~/dv/lang/hlvm$ g++ -o broken.o `llvm-config --cxxflags` broken.cpp
g++: (Debian: No such file or directory
g++: 2.2-7): No such file or directory
hendrik at lovesong:~/dv/lang/hlvm$ 


So I execute the script by itself, and get


hendrik at lovesong:~/dv/lang/hlvm$ llvm-config --cxxflags
-I/usr/include/llvm  -D_DEBUG  -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -O2 -fomit-frame-pointer -DLLVM_DEBIAN_INFO= (Debian 2.2-7) -Woverloaded-virtual
hendrik at lovesong:~/dv/lang/hlvm$ 


Putting that output into the command, and removing the
-DLLVM_DEBIAN_INFO= (Debian 2.2-7) from it, things work
as well as one might expect for a program without main():


hendrik at lovesong:~/dv/lang/hlvm$ g++ -o broken.o -I/usr/include/llvm  -D_DEBUG  -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -O2 -fomit-frame-pointer -Woverloaded-virtual broken.cpp/usr/lib/gcc/i486-linux-gnu/4.2.4/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'

Do you suppose a bug should be logged against the Debian package?
