Did you mis-type something here ? Both A and B are about select.h .
[oops.  Sorry for the mistake.  B) was bits/sigset.h.  I copied this from
x86 /usr/include/bits]

I'm not entirely sure whether this is an error on our part. In the newlib
sources, select.h is only present in newlib/libc/sys/linux/sys directory
which appears to indicate it only needs to be installed for newlib on Linux,
not for newlib on CE.

Further, MSDN points out that select should be in winsock.h, which it is in
our distributions. You'll say "I need to adapt my sources to pick that up".
Yes, but there might be a good reason for this.

If my memory serves me right, there are a few small differences between
socket implemenation on Windows and Unix/Linux. One of them is that on
Windows, they're part of Winsock, which needs to be initialized by calling
WSAStartup before it works at all.

[yes I agree with these comments.  Winsock2 implements BSD style APIs
including select.   But references
to select in source files fail in a cegcc build.  Are you saying we should
include winsock.h?
I thought that cegcc is designed to use newlib as a standalone
self-contained library.  To use winsock would it
Be better to use mingw32ce for this?]

Again, regex.h is in src/newlib/newlib/libc/sys/linux/include/regex.h
which means newlib says it shouldn't be implemented on Windows CE.

So I guess either you need to reconfigure newlib so it implements this on
WinCE, or the solution you propose yourself - to implement regex separately.
The latter is probably simpler.

[yes I made a cegcc build of regex spencer now].

Can you provide more detail ?

[Struct rlimit was missing.  Rlim_t was defined as__rlim_t and__rlim64_t 
But they are missing. So I defined these as __int32_t or __int64_t instead
Setrlimit() is missing and I just bypassed it for now.]
