// GNU C++ has a bug in the constructor which builds an ostrstream on top of a
// preallocated buffer, while dynamic strstreams work correctly
// On DEC C++ for OSF, the preallocated version works, but a dynamic strstream
// can only be inserted onto once, as it does not flex if more is added after
// the first operation 

// the use of different classes implies a difference in the finalisation needs:
// the buffer of the dynamic stream will not be released unless a freeze(0) 
// call is issued before the stream object goes out of scope, while this method
// is not defined for the preallocated version

// The -gd option generates uncompilable code with a missing 
// variable called zzTracePrevRuleName if the generated 
// files cccc.cpp, java.cpp, ada.cpp don't include a version
// of AParser.h seen with zzTRACE_RULES defined.
// I'm not sure how this is supposed to work, but for the moment
// I am including it here which should make all three files OK.
// Note that this could break again if the header files shift around
// and AParser.h gets read before zzTRACE_RULES is defined.
// Another option is turning -gd off, but its the way we do the
// cccc -dp debug output which is very useful.
