- -- have HSbase.a for static linking, not HSbase1.a and HSbase2.a.
+ -- split into HSbase1, HSbase2 and HSbase3, which is needed due to a bug
+ -- in the GNU linker (PEi386 backend). However, we still only
+ -- have HSbase.a for static linking, not HSbase{1,2,3}.a
-- getPackageLibraries is called to find the .a's to add to the static
- -- link line. On Win32, this hACK detects HSbase1 and HSbase2 and
+ -- link line. On Win32, this hACK detects HSbase{1,2,3} and
-- replaces them with HSbase, so static linking still works.
-- Libraries needed for dynamic (GHCi) linking are discovered via
-- different route (in InteractiveUI.linkPackage).
