Issue 1701192: symbol conflict for 'readahead' (original) (raw)

I'm encountering the error below with python 2.5 on current Debian x86.

src/python-2.5.1c1/Objects/fileobject.c:1845: error: conflicting types for 'readahead' /usr/include/bits/fcntl.h:187: error: previous declaration of 'readahead' was here

It may be that's it's provoked only by my slightly custom embedded build process - perhaps the standard build does not include fcntl.h while compiling this file.

A fix is trivial - just to rename the static readahead function to something else, e.g. as below.
