I reported the same problem earlier + confirmation of the volatile long
issue.
Google [error extract_insn 2083] reveals that it hit a number of
platforms but not ix86. A one line patch was posted, but that patch did
not fix the problem for the msp430, nor was it in the latest gcc-3.5
snapshot, which fails to compile anyway.
On the assumption that Dmitry had succeeded in compling msp430-libc with
some snapshot of gcc-3.4, I also tried to compile it with
gcc-core-3.4-20040331 and got the same error.
