There may be other problems, depending on how the preprocessor is 
invoked. This is the result from a system with the following:

- Sun C 5.7 2005/01/07
- gcc 4.0.1
- /usr/lib/cpp: Software Generation Utilities (SGU) SunOS/SVR4

$ cat >foo.c
sun
__sun
sun__
__sun__

$ cc -E foo.c
# 1 "foo.c"
  1
  1
sun__
__sun__
#ident "acomp: Sun C 5.7 2005/01/07"

$ gcc -E foo.c
# 1 "foo.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "foo.c"
1
1
sun__
1

$ /usr/lib/cpp foo.c
# 1 "foo.c"
1
__sun
sun__
__sun__


(This may be the first start towards the "pkgsrc guide to writing 
portable software" book. ;))
