... I initially tried to use the CPP ## string concatenation operator to create unique names (tedious, but works) but GHC runs CPP in traditional mode so that doesn't work.

One -traditional way that I have used to concatenate pieces of C code is demonstrated by:

$ cat t.c #define s(z) z s(a)s(b) $ gcc t.c -E # 1 "t.c" # 1 "<built-in>" # 1 "<command-line>" # 1 "t.c"

a b $ gcc t.c -E -traditional # 1 "t.c" # 1 "<built-in>" # 1 "<command-line>" # 1 "t.c"

ab $
