The Mac OS X version has problems, especially with quitting.
My email address is still <ctm@ardi.com>, although ARDI itself is
defunct. I get a ridiculous amount of spam and will quite possibly
not see email addressed to me. I'm ctm on github (http://github.com)

Try building the mingw32 version using the mingw32 toolchain
for Fedora 11 (mingw32 has been done before)
Try compiling a version for Mac OS X using SDL (Mac OS X hasn't been
done before, although NEXTSTEP has)
Probably want to do an in-use / marked for deletion fix

/*
* There is a very bad problem associated with the use of the db
* shared libraries under Linux. Specifically, the calling convention
* for functions which return structs that are larger than 32 bits
* somehow got changed when some of the Linux distributions switched
* from gcc to egcs. Both compilers put an extra pointer on the stack
* before calling the routine that returns the large struct, but gcc
* expects the caller to pop that extra pointer, where egcs expects
* the called to pop it. This means that if you compile the caller
* with gcc and call a shared library that was called with egcs, the
* stack pointer will be off by 4 bytes after the function returns and
* the stack is adjusted. That can be a catastrophe if further code
* expects the stack to be correct after adjustments. On the other
* hand, if we make the questionable call and then do nothing else,
* the "leave" instruction will restore the stack pointer by using the
* frame pointer and we'll never be bothered by the extra pop.
*
* So, as a workaround, we can wrap the routines, then check the
* assembly code that the compiler produces to make sure that it's
* tolerant of the error, then call the wrappers. That makes the
* wrapper routines look like voodoo code that was written by a
* superstitious programmer, but the code (or some other workaround)
* is absolutely necessary because we want to have one Executor
* executable that can run with both the shared libraries from Red Hat
* 5.2 as well as the new ones in SuSE 6.0 (and the new ones that will
* probably be in Red Hat 6.0).
*
* These wrappers absolutely have to be compiled with enough
* optimization so that the stack isn't adjusted before the leave
* instruction. If it is adjusted, then any interrupt that occurs
* between the adjustment and the transfering of the data from the
* temporary stack space to the address passed will cause corruption.
*
* If you do not understand the above, or if you disagree with it,
* please contact Cliff before changing the following code. Axing the
* code alone and then testing the result is not sufficient, unless
* you're sure that your test involves *both* db shared libaries.

/*
* There is a very bad problem associated with the use of the db
* shared libraries under Linux. Specifically, the calling convention
* for functions which return structs that are larger than 32 bits
* somehow got changed when some of the Linux distributions switched
* from gcc to egcs. Both compilers put an extra pointer on the stack
* before calling the routine that returns the large struct, but gcc
* expects the caller to pop that extra pointer, where egcs expects
* the called to pop it. This means that if you compile the caller
* with gcc and call a shared library that was called with egcs, the
* stack pointer will be off by 4 bytes after the function returns and
* the stack is adjusted. That can be a catastrophe if further code
* expects the stack to be correct after adjustments. On the other
* hand, if we make the questionable call and then do nothing else,
* the "leave" instruction will restore the stack pointer by using the
* frame pointer and we'll never be bothered by the extra pop.
*
* So, as a workaround, we can wrap the routines, then check the
* assembly code that the compiler produces to make sure that it's
* tolerant of the error, then call the wrappers. That makes the
* wrapper routines look like voodoo code that was written by a
* superstitious programmer, but the code (or some other workaround)
* is absolutely necessary because we want to have one Executor
* executable that can run with both the shared libraries from Red Hat
* 5.2 as well as the new ones in SuSE 6.0 (and the new ones that will
* probably be in Red Hat 6.0).
*
* These wrappers absolutely have to be compiled with enough
* optimization so that the stack isn't adjusted before the leave
* instruction. If it is adjusted, then any interrupt that occurs
* between the adjustment and the transfering of the data from the
* temporary stack space to the address passed will cause corruption.
*
* If you do not understand the above, or if you disagree with it,
* please contact Cliff before changing the following code. Axing the
* code alone and then testing the result is not sufficient, unless
* you're sure that your test involves *both* db shared libaries.
