gdb-970817 vs i386-pc-solaris2.5.1

[Jim Meyering]

Hi,

I have the misfortune to run solaris2.5.1 on my nice dual P200 Vectra.
I tried to build gdb-970817 using this version of egcs:

  Reading specs from /p/lib/gcc-lib/i386-pc-solaris2.5.1/egcs-2.90.06/specs
  gcc version egcs-2.90.06 970907 (gcc2-970802 experimental)

My first compile failed because neither R_PSR nor PS_FLAG_CARRY was defined.
Here's a kludge to work around that.

Next attempt failed because TIDGET is not defined and hence,
procfs_pid_to_str (used below) is not defined.  Here's the really ugly
kludge I used to work around that.

Finally, I got this (inexplicable to me) link error:
