Addressing my suggestions was not intended as a prerequisite for
committing your previous version.

The new version seems to have at least one actual problem though:
the way that the buffer array is managed.  Its allocation/deallocation
strategy should be consistent (probably "new char[]" and "delete[] char")
regardless of the availability of the various *sprintf variants.  It should
probably not even be in #if/#endif markers.  The new code appears to be
able to hit free() even though malloc() was never called.
