Move your "static" declarations in functions out to the top level of
the file, from:

main()
{
	static int big[30000];
	/* lotsa stuff */
}

to 

static int big[30000];
main()
{
	/* lotsa stuff */
}

The same thing happens under Microsloth C.  Pain in the ass, and nasty
for scoping, but Intel real mode is Intel real mode...

One other suggestion is to declare any large structures of arrays
to be far. This will force them into their own data segment and
allow the Large Model to link without incident. Under Large Model,
far pointers are the rule, but they only operate 16 bit offsets, so
the largest structure or declaration(s) you can have must not total
more than 64K per segment . Also be aware that storage space is required for
arrays and structures so you can not legally declare something
like:

char foo[65535];

because of the storage space required to declare and utilize the
array at runtime. If you need to have larger structures, then use
Huge Model, which uses true 32 bit (normalized) pointers.

Are you using C++ specific code?  If so, you can use the -Vf switch for BCC,
or look for a switch in the IDE which moves the C++ virtual tables out of 
the data segment.  

Basically, this error means that your global variable area has exceeded 64k.
Evidently, Borland puts their virtual tables (or at least some information 
concerning them) into this segment.
