Comment (by erikd):

 The code in question from includes/stg/Regs.h is:

 {{{
 #if defined(REG_Base) && !defined(NO_GLOBAL_REG_DECLS)
 GLOBAL_REG_DECL(StgRegTable *,BaseReg,REG_Base)
 #define ASSIGN_BaseReg(e) (BaseReg = (e))
 #else
 #if defined(THREADED_RTS) && !defined(NOSMP)
 #error BaseReg must be in a register for THREADED_RTS
 #endif
 #define BaseReg (&((struct PartCapability_ *)MainCapability)->r)
 #define ASSIGN_BaseReg(e) (e)
 #endif
 }}}

 The git log suggests this file hasn't changed in over a year.
