At the moment, GDB doesn't have any support for a 10-byte long double
type.  Our long doubles are twelve bytes long, since that's how the C
compilers lay them out.

One could certainly add support to GDB for this.  If your compiler
emits debugging information in a helpful way, it could be reasonably
clean.

However, I think you might want to consider changing your compiler to
use 12-byte long doubles, aligned on a four-byte boundary.  This would
make it easier for Pascal and C code to share data.  Also, the Intel
x86 processor manual says that aligning objects improves performance;
this is why the C ABI requires four-byte alignment.
