Problem building scsh 0.4.4

[Stephen Pascoe <stephenp@mi.leeds.ac.uk>]

I am trying to compile scsh 0.4.4 on an SGI R5000, IRIX 6.2.  The
makefile keeps failing on the following target:

          gcc -c -I./cig -I./scsh/regexp -DHAVE_CONFIG_H -I. -I. \
  -O -o scsh/sighandlers1.o scsh/sighandlers1.c
  scsh/sighandlers1.c: In function `set_procmask':
  scsh/sighandlers1.c:41: structure has no member named `sigbits'
  scsh/sighandlers1.c:44: structure has no member named `sigbits'
  scsh/sighandlers1.c:44: structure has no member named `sigbits'
  scsh/sighandlers1.c: In function `get_procmask':
  scsh/sighandlers1.c:55: structure has no member named `sigbits'
  scsh/sighandlers1.c:55: structure has no member named `sigbits'
  *** Error code 1 (bu21)

Can anyone be of any assistance?

Stephen.
