Rebuilding netkit-rsh 0.17-r9 (as part of system rebuild) after updating glibc
from 2.7-r2 to 2.8_p20080602, I get the following error:

!!! ERROR in net-misc/netkit-rsh-0.17-r9:

This is the same error as bug 225409.

See
http://www.nabble.com/FYI:--glibc-2.8-may-break-some-of-your-packages-td16625128.html

"glibc 2.8 no longer defines ARG_MAX constant in linux, so you may see:


foobar.c:N: error: 'ARG_MAX' undeclared (first use in this function)

To fix this problem you can use something like this

#include <unistd.h> /* only if not already there !! */

#if defined(_SC_ARG_MAX)
# if defined(ARG_MAX)
#    undef ARG_MAX
# endif
# define ARG_MAX sysconf (_SC_ARG_MAX)
#endif"
