Hi!

The problem is that most Linux version needs the inclusion of
asm/termbits.h to work.  It seams that glibc 2.1 doesn't allow this
anymore (which is probably correct).  To fix this, one has to add a
new test to configure to check if one has to include asm/termbits.h
anymore.

I don't have access to a glibc 2.1 system to check this, so I am
greatfull if anyone can fix configure to not define HAVE_ASM_TERMBITS
when used with glibc 2.1.

Monty
