Olly, thanks for looking into it some more. I'm not sure why my file sizes
were so big.
I looked up the versions I'm compiling with. This is a Red Hat Enterprise AS
How do you record those real/user/sys times?
Here's my xapian-bindings-0.8.3/php4/.libs result, after compiling with the
default settings (like I did for 0.8.1):
-rwxrwxr-x 1 boone boone 10583062 Oct 19 10:16 xapian.so
-rw-rw-r-- 1 boone boone 14722568 Oct 19 10:16 xapian_wrap.o
The 3.7MB stripped version works OK for me, so for now I'm not worried about
it, but it would be nice to get the small files you're seeing.

Your numbers don't even slightly agree with mine!
I'm using Debian "unstable" on x86. My GCC is "version 3.3.5 (Debian
I compared 0.8.1 to CVS HEAD, but nothing relevant to PHP has changed
since 0.8.3 that I can see.
0.8.1 builds in:
-rwxr-xr-x 1 olly olly 856502 Oct 21 05:06 xapian.so*
-rw-r--r-- 1 olly olly 1073848 Oct 21 05:06 xapian_wrap.o
-rwxr-xr-x 1 olly olly 811052 Oct 21 05:19 xapian.so*
CVS HEAD builds in:
-rwxr-xr-x 1 olly olly 1987134 Oct 21 03:09 xapian.so*
-rw-r--r-- 1 olly olly 2566252 Oct 21 03:09 xapian_wrap.o
-rwxr-xr-x 1 olly olly 789964 Oct 21 05:12 xapian.so*
So I get nothing like 10MB, and CVS HEAD is *smaller* than 0.8.1 once
The build *is* a lot slower though. The main differences between
the builds are that 0.8.3 builds with "-O2 -g" whereas 0.8.1
is unoptimised and without debug.
So I suspect whatever GCC version you're using produces larger
code with -O2 compared to no optimisation than mine does.
Depending how much of the difference is optimisation and how much is
debug, perhaps we should modify configure so -g isn't passed by default
but only if configure is run with --enable-debug. I'll give that a
go and see.
