[Nescc-bugs] mig doesn't handle nx_union, nescc 1.2.4

[Geoffrey M. <mai...@ee...>]

This is using the 1.2.4 compiler with the TinyOS 2.x tree (dev branch):

mig java -target=telosb -java-classname=CollectionDebugMsg \
$TOSDIR/lib/net/collection/CollectionDebugMsg.h CollectionDebugMsg \
>CollectionDebugMsg.java

Look at the offsets in CollectionDebugMsg.java. The nx_union isn't
handled properly: it's treated as a struct declaration.

Using 1.2.6 gives me the same internal error as my previous post.

Note that mig also get sizes wrong when setting the size of a
typedef with an attribute, e.g,

int __attribute__((__mode__(__DI__)))  myint64_t;
