It is important to add a note to the INSTALL.OS2 which I would rename
INSTALL.OS2-EMX that the libraries produced by this process can only
be used with EMX applications. These libraries cannot be used with
code produced with the IBM Compilers due to conflicts between the EMX
and IBM C Run-time environments.
> This patch adds the ability to build shared libraries (DLLs) for the OS/2
> platform. It's a diff against the current 0.9.7-stable branch but should apply
> cleanly to HEAD too. Although I've touched a few bits of code that are used
> for the Win32 build in mkdef.pl I've verified that the output generated by it
> for windows targets is unchanged. The output for VMS does change a little but
> looks quite broken anyway (EXETYPE WINDOWS?).
>
> The included changes to util/libeay.num were generated, not hand edited, so a
> make update won't clobber them.
