Subject: Fix macro redefinition for GNUC compilers > 6
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=118d5cc03f587dcf97740606f8b4552749f849bc;hp=8f02375cc6ddfbbc6be384a9d5b1a9c91517099e;p=qmk_firmware.git

Fix macro redefinition for GNUC compilers > 6

GNUC compilers greater than version 6 already have the macro __always_inline defined. This fix checks GNUC version before defining the macro itself.
