Odd, I just tried your example and it built fine for me.  I am using a slightly
newer toolchain, though.  I'll have someone look into this.

Can you send me the "compile & link" commands that were used to build/link your
program?  What I did was to copy your test program into the "io/serial/XXX/tests/"
directory and adjust the makefile.  Here's the output from the build:

[gary@hermes aeb_test]$ make -C io/serial/current/tests/
make: Entering directory `/work/aeb_test/io/serial/current/tests'
arm-elf-gcc  -c  -I/work/aeb_test/install/include -I. -I/work2/ecc_mainline/ecc/io/serial/current/tests -mcpu=arm7di -Wall -Wpo
inter-arith
-Wstrict-prototypes -Winline -Wundef -ffunction-sections -fdata-sections -mno-sched-prolog -g -O2   -Wp,-MD,io_serial_aeb_test.

io_serial_aeb_test.o aeb_test.c 
arm-elf-gcc -o /work/aeb_test/install/tests/io_serial/aeb_test io_serial_aeb_test.o -mcpu=arm7di -Wall -Wpointer-arith -Wstrict

 -Ttarget.ld -nostdlib

Note: on my system, I work with the 'current' version.  The path will be slightly
different on yours.

Also, you'll want to open "/dev/ser0", not "/dev/serial0".  You also need to enable
it, either using the ConfigTool if you are using Windows, or by editting the file
"pkgconf/io_serial.h"
