my version of spatch (?) does not like this construct.
$ spatch --version
spatch version 1.0.6-00036-gb62df17 compiled with OCaml version 4.02.3
Flags passed to the configure script: --prefix=/usr
Python scripting support: yes
Syntax of regular expresssions: PCRE
Is this something new, or am I doing something wrong ?
I played with it myself, and came up with the (less elegant) version
below. It isn't perfect (it does not handle the function-in-macro case
well), but it should give us a good comparison. Also, I might just get
rid of at least some of those macros; they just obfuscate the code anyway.
Thanks,
Guenter
