Re: Issues w/ cross-compiling

Hi,

Before all, I want to thank both of Ralf, Philip for
interesting discussion. The reason why I'm working with
bcc is the investigation on non-GNU developement tools,
so Ralf's comment is very suggestive for me.

Great thank you for suggestion. Yes, by using "elksemu",
checking for the size of types would be more exact.
Should I write elksemu-specific checking? e.g., checking
the target is ELKS, system has "elksemu" (and it works),
then several checks are executed by elksemu.
If Autoconf has any existing macros to utilize such
emulatior command, please let me know. I don't think
such commandline emulator is popular (I guess, today
virtual machine solution are prefered), so I don't
hesitate to write ELKS-specific macros.
