Cannot compile postgresql 6.3

System : RedHat Linux i386 4.2
Hardware : Pentium 200 MMX
Pg 6.3 Snapshot : Dated on February 23

After ./configure and gmake all I am getting this error :

gcc -I../../include -I../../backend -I/usr/include/ncurses
-I/usr/include/readline -O2   -Wall -Wmissing-prototypes -I..   
-Wno-error   -c bootstrap.c -o bootstrap.o
bootstrap.c:160: `F_BOOLIN' undeclared here (not in a function)

bootstrap.c:162: `F_CHARIN' undeclared here (not in a function)
bootstrap.c:162: initializer element for `Procid[2].inproc' is not

...
there are a lot more, and compiling is stopping.

Please cc me because I am not on the pgsql-questions@postgreSQL.org list
