Subject: Incomplete dependencies for libio/old*.c
Date: Sun, 27 Apr 2003 16:11:00 -0000 [thread overview]
Message-ID: <m3k7dg9kwn.fsf@whitebox.local> (raw)
Dependencies are generated using the non-pic command line (ie. without
-DSHARED). This is a problem with some of the compatibility sources
which check SHLIB_COMPAT before including the headers, so that the
generated dependency list is incomplete.
Andreas.
