What is the strict aliasing rule?
...ict aliasing in your compiler (f[no-]strict-aliasing in gcc))
You can use char* for aliasing instead of your system's word. The rules allow an exception for char* (including signed char and unsigned char). It's always assumed that char* aliases other types. However this won't work the other way: th...
In Python, how do I create a string of n characters in one line of code?
I need to generate a string with n characters in Python. Is there a one line answer to achieve this with the existing Python library? For instance, I need a string of 10 letters:

Then you can select the relevant stuff depending on detected_OS:

CFLAGS += -D WIN32
endif
ifeq ($(detected_OS),Darwin) # Mac OS X
CFLAGS += -D OSX
endif

public:
Foo(char x, int y) {}

C++03: No
Unfortunately, there's no way to do this in C++03, but there are two ways of simulating this:
You can combine two (or more) constructors via default parameters...
