  98 This is an internal method that returns path to a library which
  99 should be put on the linker command line I<after> the external libraries
 100 to be linked to dynamic extensions.  This may be needed if the linker
 101 is one-pass, and Perl includes some overrides for C RTL functions,
 102 such as malloc().

 123 ExtUtils::MM_OS2 - methods to override UN*X behaviour in ExtUtils::MakeMaker
 124

 130
 131 See ExtUtils::MM_Unix for a documentation of the methods provided
 132 there. This package overrides the implementation of these methods, not
 133 the semantics.
