http://wooledge.org/mywiki/BashFAQ#faq31 explains the differences between [[
and [, although in this case I'd use:
if ((gcc-major-version>3 || (gcc-major-version==3 && gcc-minor-version>3) ))
"As a rule of thumb, [[ is used for strings and files. If you want to
compare numbers, use an ArithmeticExpression."
