[fpc-pascal] FPC 3.0 and FPC 2.6 on Ubuntu. How to change default version?

[Krzysztof]

Hi,

Need to have both FPC versions, 2.6 for all old projects (a lot) and
3.0 for new ones (only one for now). Installed 3.0 from debs (2.6 is
also from deb packages). While installing got info that there is
another FPC version and /etc/fpc.cfg need to be changed for switching
between default versions. Allowed that. Now 3.0 becomes default and I
would like to have 2.6 as default since more projects use it. Looking
at fpc.cfg and can't find what need to be changed for make 2.6 as
default. For example, have lazarus fixes_1_6 svn repo and 'make'
command should always use FPC 2.6
