Further compile problems on Solaris 2.5/2.5.1

[Andrew Gilmore <gilmorea@fluvial.Colorado.EDU>]

Ok, got one more set of compile problems with 3.1.19:

gmake[2]: Entering directory `/fluvial/pstaff/gilmorea/zipfiles/temp/siag-3.1.19/plugins'

[SNIP]

gcc -DHAVE_CONFIG_H -I. -I. -I..    -Wall -g -O2 -c clipart.c
clipart.c: In function `save_file':
clipart.c:1112: `sys_errlist' undeclared (first use this function)
clipart.c:1112: (Each undeclared identifier is reported only once
clipart.c:1112: for each function it appears in.)
clipart.c:1114: `sys_nerr' undeclared (first use this function)
gmake[2]: *** [clipart.o] Error 1

Appears to be some system structures related to IO, but I am unable to find
any such structures on my systems. (Grep in /usr/include and below,
/usr/local/include and below,
/usr/local/lib/gcc-lib/sparc-sun-solaris2.5/2.7.2/include and below)
