[gccsdk] no tabs in a program compiled with GCC 4.7.4 release 6 with -mlibscl option

An observation I made when running GCC 4.7.4. release 6 with the -mlibscl option used is that no tab spacing (\t) is present in the compiled program, which leaves me wondering if it is a bug or not. It doesn't matter whether I double-click or run the program from the task window; there is no tab spacing in the output.

In contrast, when I compile with -static and elf2aif, the tabs are there.

Is it a bug with other side effects? Or expected behaviour?

All the best,

Andrew
