#! /bin/sh
# Wrapper around IBM C++ compiler to add "-+" to preprocessor calls
# and thus work with C++ in files other than *.C.  Also add -Wc,lang(longlong)
# with appropriate quoting to avoid shell confusion -- this is difficult 
# to get through both ./configure arguments _and_ Makefile/shell expansion
# safely so more easily added in this wrapper.
#
# Finally, by default will enable xplink for C++ compatibilty and performance
# (c++ standard library requires xplink enabled).
#
# Additional compile/link flags can be passed in as ZCXXFLAGS, eg:
#
# For debug:  ZXCCFLAGS=-g ...
