Thanks for fix suggestion, PKGBUILD updated. Additionaly applied '-Wno-error=stringop-truncation'

Currently I'm not using this, feel free to request orphan.

The following needs to be added to build():

  CFLAGS+=' -Wno-error=deprecated-declarations -Wno-error=lto-type-mismatch -Wno-error=stringop-overread -Wno-error=stringop-overflow='
  export CFLAGS

Otherwise there are build errors:
