One can include newlib.h to perform some checks against the used newlib library.
Problem is that version 1.110301.0 contains broken arm-none-eabi/include/_newlib_version.h which contains e.g.
#define __NEWLIB__ @NEWLIB_MAJOR_VERSION@
#define __NEWLIB_MINOR__ @NEWLIB_MINOR_VERSION@
#define __NEWLIB_PATCHLEVEL__ @NEWLIB_PATCHLEVEL_VERSION@
Which is syntactically wrong.
Sadly, also upstream 11.3.Rel1 contains this broken file but upstream 12.2.Rel1 is fine again.
Is there a way how this can be fixed? I mean downstream in toolchain-gccarmnoneeabi.
I can skip this broken version and pin the project to an older one to workaround this.
For comparison, this file in other toolchain-gccarmnoneeabi versions
