 270 # such flag is given in the command line, libtool attempts to figure

 272 # against a prefix of the command line.  The problem is that, if the
 273 # compiler name and its initial flags stored in the libtool
 274 # configuration file don't match those in the command line, libtool
 275 # can't decide which configuration to use, and it gives up.  The
