glibc is bloated, printf and strtoul are also quite large. Try dietlibc
; diet gcc -c -Os testit.c
; size testit.o
text data bss dec hex filename
289 0 0 289 121 testit.o
; diet gcc -o testit -s -Os testit.c
; size testit
text data bss dec hex filename
9620 0 12 9632 25a0 testit
So the libraries come to over 9k, and there is still some
crud in the image:
; objdump -h testit
testit: file format elf32-i386

Why do I need an exception handler frame (assuming that is what
the name means)?
