[Scilab-Dev] 1 boolean = 4 bytes => 1 byte ?

[Samuel Gougeon]

Hello,

As reported  @ http://bugzilla.scilab.org/12789 in 2013 (so 2 years 
before the first 6.0 alpha release), in Scilab 5 each boolean takes 4 
bytes to be stored.

It is 4 times more than an easy storage and handling with 1 byte per 
boolean, and 32 times more than a memory optimum with 8 booleans per byte.

Since [names, memory]=who(..) is broken in Scilab 6, i did not check 
that this poor memory usage is still actual in 6.0.

Assuming that it is the case, then, what would imply to change the 
storage -- say with 1 byte per boolean --

  * in terms of implementation : would it be heavy to implement?
  * in terms of back-compatibility : would it have a big impact?

Regards

Samuel
