Gcc doesn't have any choice in the matter.  All it knows is that there's
a C library on the system, that's it.  It doesn't know nor care where or
how the C library is implemented.

In the case of Cygwin, the C library is provided by Cygwin, in the form
of cygwin1.dll.  Cygwin relies on newlib to implement some things, but
malloc is not one of them.
