Use bit-fields:

struct {
  bool a : 1;
  bool b : 1;
  bool c : 1;
  //...
};

Edit: careful not to use a 1-bit signed int, since the only values are 0 and -1, not 0 and 1. This tripped me up once.

In a world where a bigger memory chip is more expensive by only a few cents where this would be most useful, is this feature still relevant?

Yes, firmware running on bare metal requires good resource management. My current development board processor contains 512KB SRAM. That's equivalent to half of the size of an average PDF.
