Comment (by guest):

 The situation: I am building 6.4.1 using 6.4.1. The installed version was
 by a package installer. Now I want to build a source myself, since I want
 to see if I can change some things. After the usual stuff and doing make I
 obtain this error message:

 utils/PrimPacked.lhs:263:0:

 Having looked at it for a while and discussing the problem with Arthur van
 Leeuwen, we decided that the problem is that the build system uses the
 HsUnix?.h file of the existing distribution, and not the one from the
 sources. The problem arises because these two files are different.

 Having looked at it a bit closer, the discrepancy turns out to be between
 two ghcautoconf.h files.
