run the test suite
This doesn't work with out-of-source-tree builds. You need to prepend getenv("srcdir"), cf. https://dev.gnupg.org/source/libassuan/browse/master/tests/common.h;859f9a9754708572a6289853d7d95b9ee3eae589$197
You can't include this unconditionally.
Pleade don't use "fd" for FILE object. "fp" or "stream" are commonly used names.
Remove use of mmap(), allow out-of-source builds.
