Using old gcc. How to do? Is it safe?
I have lenny Penguin, with gcc-4.3.
I need to use older gcc's (4.2 or 4.1) to compile. Makefile is complicated (many children, grandchildren) so that I am reluctant to modify them. I know how to switch under MacOSX, but not debian.
How to do?
I installed older versions using aptitude, then made links (gcc and g++).
Web search says that "ccontrol" takes care, but I could not figure out how it works.
Does it make my penguin unstable? Is binary stable?
Thank you for replies.
