Very good point Jonathan....
You can install GCC 4.7 first, as that can be built using only a C
compiler. Then use GCC 4.7 to build GCC 5.2
Ok. This is what IÂve decided to do... In real a good path to solve my problem.
IÂve now downloaded and tried to compile the Gcc 4.7.0 version and now
seens that IÂm having problems with link libraries:

I need help to move this step foward and be ready to install the 5.2 version.
Thanks!
