a94d82e6f9 Always use NetBSD's fts(3) in compat builds. Some systems (notably 
Red Hat 7.3, at least) do not have fts(3) implementations that work
correctly with -D_FILE_OFFSET_BITS=64.

daf4d5c635 Fix some problems using makelintstub as a cross-tool: 
* Require that the path to the C preprocessor be passed in the CPP
  environemnt variable, and use it rather than hard-coding "cpp".
  Provide the target's preprocessor when invoking makelintstub.
* Fix some quoting issues that turned up with Solaris 8's XPG4 sh and sed.
* Don't use echo -n.  Instead, don't bother making the output pretty; the
  whitespace isn't supposed to be syntactically significant anyhow.

2e409d7d44 Fix a signal handler bug originally reported by Hugh Graham some year ago: 
If two signals are sent after each other without the process being run in
userspace between them then the second one will overwrite part of the signal
info stored on the userstack.
Fixed by rewriting and simplifying both the signal delivery code and the
trampoline code. Also bump signal version number to 2.
Rename __sigtramp1.S to __sigtramp.S.

f89823c1f8 Save 1-4 instructions on all cases except for the ret=0 case. 
This is probably the last version from me. :)
You are welcome to speed it up, of course. :)

Here's a benchmark on SH-4 200MHz.
9.2% faster if all the cases occur evenly.

fa5465079f Slightly improved version of ffs(3). 
Partially from SHIMIZU Ryo <ryo@iij.ad.jp>.  Thanks.
Some cases are slower, but other most cases are faster.

Here's a benchmark on SH-4 200MHz.

70b5675025 Assembly version of ffs(3). 
Confirmed to return the same value as that of the C version.

The results of a simple benchmark on SH-4 200MHz, is shown below.
I think this shows acceptable performance.
