Bug #776: PGSQL 7.2.2 build broken on OS X 10.2

Lee Nelson (jld123(at)pobox(dot)com) reports a bug with a severity of 1
The lower the number the more severe it is.

Short Description
PGSQL 7.2.2 build broken on OS X 10.2

Long Description
Postgresql 7.2.2 does not build on Mac OS X 10.2 . Worked perfectly on OS X 10.1.4. Developer disk (GCC, etc) is installed.

To reproduce:

./configure
make

Failure Output (last few lines from build):

make -C darwin all
gcc -traditional-cpp -g -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I../../../../src/include -c -o sem.o sem.c
In file included from sem.c:30:

make[3]: *** [darwin.dir] Error 2
make[2]: *** [port-recursive] Error 2

SUGGESTIONS or WORKAROUNDS appreciated.

Thank you,
