Hi Al,
starting from kernel 2.6.23, linux/limits.h doesn't longer export
OPEN_MAX macro.
There are two testcases using it (pipe_test02.c and fork09).
Wherever it is possible, I defined OPEN_MAX as an alias for a sysconf call,
otherwise I fixed its value.
This patch applies to 20070731 release, but should works fine for latest
release
Kind regards,
Carmelo
Define OPEN_MAX not being exported by kernel headers.
Wherever it's possible, use the sysconf function, otherwise
hard code its value
