Subject: Improve check for GCC compiler version
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ac0ab65ebcd7b11739986b81343457469fbb43b0;p=mtd-utils.git

Improve check for GCC compiler version

When using unreleased compiler has version like
15.0.1 and that test fails because __GNUC_MINOR__ < 1
becomes true, therefore check for full version string
which is more rubust.
