The preproc code doesn't need to be thread-safe does it?
One issue we already fought with for large-file support is that that
#define _REENTRANT probably needs to appear before you start to include
any system header files. You may find that the best way to handle it
is to make it a "-D_REENTRANT" added to CPPFLAGS (only within ecpg/lib),
rather than trying to find a safe place to put it in the .h files.
