134 # be overridden by --enable-debug.)
136 # 2) In general, libtool expects an argument such as `--tag=CXX' when
137 # using the C++ compiler, because that will enable the settings
138 # detected when C++ support was being configured. However, when no
139 # such flag is given in the command line, libtool attempts to figure
140 # it out by matching the compiler name in each configuration section
141 # against a prefix of the command line. The problem is that, if the
142 # compiler name and its initial flags stored in the libtool
143 # configuration file don't match those in the command line, libtool
144 # can't decide which configuration to use, and it gives up. The
145 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
146 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
147 # attempt to infer which configuration to use

153 # be used in libtool since this would add -lstdc++ to the link line
154 # which of course is problematic at this point.
