porting postgresql 7.0.3 to linux on SH3

Dear Sir,

When I tried to port postgresql 7.0.3 to linux on SH3,
I cannot compile the s_lock.c under the
src/backend/storage/buffer directory. The errors are
as follows:

gcc -I../../../include -I../../../backend -O2 -Wall
-Wmissing-prototypes -Wmissing-declarations -I../..
-c -o s_lock.o s_lock.c
s_lock.c:47: warning: type defaults to `int' in
declaration of `slock_t'

function)
s_lock.c:84: `line' undeclared (first use in this
function)
make[3]: *** [s_lock.o] Error 1

Is there any way to fix the compliler errors?

Any help will be highly appreciated!
