Postgresql 7.0.3 - compilation failure. Need help.

System Configuration
---------------------
Architecture (example: Intel Pentium) : Sparc

Operating System (example: Linux 2.0.26 ELF) : SunOS 5.8 (Solaris 8)

PostgreSQL version (example: PostgreSQL-6.5.2): PostgreSQL-7.0.3

Compiler used (example: gcc 2.8.0) : gcc 2.95.2

Postgres failed to compile on my system with or without any configuration options.

'gmake' died with this error message every time I tried to compile:

gmake[2]: Entering directory `/home/packages/src/postgresql-7.0.3/src/backend/lib'
gcc -I../../include -I../../backend -O2 -Wall -Wmissing-prototypes -I.. -c stringinfo.c -o stringinfo.o

../backend/nodes/list.c also had the same error with 'va-list' being undeclared.

Thanks,
Latha.
