Already fixed in trunk.

Doesn't seem to matter, I get this was well and the build still works.

Please could you give the output of the "patch" command so that we can see 
if e_os2.h is actually being patched or not?

I agree that 0.9.8j would be better, but it takes quite some effort to 
update the patch as the makefile.one build method is not supported or 
maintained by the OpenSSL folks, and consequently many object files are 
missing which are needed to compile the rest of OpenSSL, and the patch 
has to add all of those. I.e. even if the patch succeeds, OpenSSL will 
still probably not build. I'd rather that the OpenSSL folks came up with a 
proper, supported way of cross-compiling OpenSSL.

I haven#'t tried 7.8, but if it works for you (i.e. libpcreposix.a is 
built by "make") then let me know and I'll update the docs to use it 
instead.

I'd prefer not to add another DLL that we have to distribute, i.e. I 
prefer static linking.

Already fixed in trunk.

Please could you try again with trunk?
