# 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 ...
