The actual build failure is not in the part of the log Matthias quoted,
but it seems to be this:

In file included from cmdlib.h:6,
                  from qcc.h:7,
                  from qccmain.c:4:
progsint.h:25:22: error: cannot use keyword ‘false’ as enumeration constant
    25 |         typedef enum{false, true} boolean;
       |                      ^~~~~

Probably compiling with -std=gnu17 would be a workaround for this.
