problem building 2.1 on SunOS 5.7

[Garry Hodgson]

i'm trying to download python 2.1 on a new machine, and having 
some problems.  i do a configure, then a make, and get:

->make
gcc -c -g -O2 -Wall -Wstrict-prototypes -I. -I./Include -DHAVE_CONFIG_H 
-o Modules/python.o Modules/python.c
In file included from
/usr/local/lib/gcc-lib/sparc-sun-solaris2.4/2.7.2/include/time.h:90,
                 from /usr/include/sys/time.h:405,
                 from /usr/include/sys/select.h:17,
                 from
/usr/local/lib/gcc-lib/sparc-sun-solaris2.4/2.7.2/include/sys/types.h:274,
                 from /usr/include/sys/wait.h:20,
                 from
/usr/local/lib/gcc-lib/sparc-sun-solaris2.4/2.7.2/include/stdlib.h:17,
                 from Include/Python.h:50,
                 from Modules/python.c:3:
/usr/include/sys/siginfo.h:74: parse error before `pthread_attr_t'
/usr/include/sys/siginfo.h:74: warning: no semicolon at end of struct or
union
/usr/include/sys/siginfo.h:76: parse error before `}'
*** Error code 1
make: Fatal error: Command failed for target `Modules/python.o'

the same thing happens with 1.6.1

it works ok on another machine running SunOS 5.6.
does anyone know of a fix/workaround?

thanks
