On the other hand, instead of "if (win98)..." one could have a cygwin1.dll that chooses a 2nd library to load and all entry points are either runtime indirect calls into the 2nd library (cygwin_NT, cygwin_nont). The user could optimize by manually running a script that copied the OS specific library in place of cygwin1.dll and setting a flag in an /etc/sysconfig/libpref file so future updates of the library could automatically install the OS-specific version when updating the library. To keep the option of what OS to use open, the "pointer-lib" could be renamed to cygwin1_wrapper.dll when not used as the default. BTW -- what % of users are still on win9x/me? Is there any obsolescence plan (not that I am pushing for such!)... Just some ideas to mull around if a leaner memory footprint became something of a priority... linda Christopher Faylor wrote: >OTOH, Corinna is hard at work adding low-level Nt* calls to cygwin so, >if it wasn't for the requirement that everything has to work on Windows >9x, the DLL would be smaller and faster.
