openssh unix dev - Feb 2001 - Compile problems with 2.5.1p1 and older Linux boxes

Hi,

I'm having problems building 2.5.1p1 on two of my older Linux boxes.  One
box is running RH 5.2 and the other Debian 2.0.  Both are using gcc 2.7.2.3,
openssl-0.9.6 and glibc-2.0.7.  They both also die on the same error, and the 
configure options I use don't seem to make a difference.

2.3.0p1 compiled fine on both of these machines.

Thanks for your help!

That was me.  It turns out that sigaction.h isn't included in signal.h
for some reason.  I had to manually insert it to get it to work.
Someone else emailed me with the same problem.

BTW: I'm using gcc-2.7.2.3.
