That is, when the linker sees
  -lXYZ
it looks for
  libXYZ.a

Actually, the msw version looks for some other files too:
  http://sourceware.org/binutils/docs-2.16/ld/WIN32.html

But if you say '-llibXYZ', it looks for 'liblibXYZ.a', which
is unlikely to exist. There actually is a library called
'libiberty', though; it has that odd name to make '-liberty'
work. Understanding that example is a good way to remember
now the name typically gets transformed.

Presumably, it does, but the headers you used didn't.
