Need help building for STM32F4DISCOVERY

An update on this situation.

Now that I've had some time, I tried going backwards through compiler versions, in addition to the one I had previously mentioned. These are the versions I tried:

arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 7-2018-q2-update) 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907]

arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 7-2017-q4-major) 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204]

arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 6-2017-q2-update) 6.3.1 20170620 (release) [ARM/embedded-6-branch revision 249437]

I can report that only the last one (6-2017-q2-update) worked. So it looks like some work is needed to make it build using the newest compilers. If I have time, I'll try to figure out what's broken.
