Comment:

 This fails on MacOS 10.7.5 and 10.8.4. Here is the output from 10.7.5:

 {{{
 Wrong exit code (expected 0 , actual 2 )
 Stdout:
 ----- 0 ------
 (0,"[1 of 2] Compiling B                ( B.hs, B.o )")
 (0,"[2 of 2] Compiling Main             ( A.hs, A.o )")
 ----- 1 ------
 (1,"[2 of 2] Compiling Main             ( A.hs, A.o )")
 ----- 2 ------
 (2,"[1 of 1] Compiling Main             ( C.hs, C.o )")
 (2,"Linking A ...")

 Stderr:

 make[1]: *** [T7478] Error 1

 *** unexpected failure for T7478(normal)
 }}}

 Please let me know if any further info is needed!
