-ExtUtils::MM_OS2 - methods to override UN*X behaviour in ExtUtils::MakeMaker
+This is an internal method that returns path to a library which
+should be put on the linker command line I<after> the external libraries
+to be linked to dynamic extensions.  This may be needed if the linker
+is one-pass, and Perl includes some overrides for C RTL functions,
+such as malloc().
