107 # Apparently, some versions of SCO include both .so and .a libraries,
108 # but they don't mix as they do on other ELF systems. The upshot is
109 # that Configure finds -ldl (libdl.so) but 'ld' complains it can't

112 # -dl from libswanted for all SCO systems until someone can figure
113 # out how to get dynamic loading working on SCO.
