/*
I initially attempted to directly wrap gcc's:
diagnostic_report_diagnostic()
given that that seems to be the abstraction within gcc/diagnostic.h: all
instances of (struct diagnostic_info) within the gcc source tree seem to
be allocated on the stack, within functions exposed in gcc/diagnostic.h
However, diagnostic_report_diagnostic() ultimately calls into the
pretty-printing routines, trying to format varargs, which doesn't make much
sense for us: we have first-class string objects and string formatting at
the python level.
Thus we instead just wrap "error_at" and its analogs
