Hi Eric,
The lseek configure-time test fails not only on mingw, but also on BeOS.
Here is a proposed fix.
2007-08-18 Bruno Haible <[EMAIL PROTECTED]>
* lib/lseek.c: Include <sys/stat.h>.
(rpl_lseek): Add workaround code also for Unix platforms.
Needed for BeOS.
* doc/functions/lseek.texi: Document BeOS definiency.
