+The @code{g77} driver now ensures that @samp{-lg2c}
+is specified in the link phase prior to any
+occurrence of @samp{-lm}.
+This prevents accidentally linking to a routine
+in the SunOS4 @samp{-lm} library
+when the generated code wants to link to the one

 @code{g77} no longer crashes when compiling code
 containing specification statements such as
 @samp{INTEGER(KIND=7) PTR}.
