Subject: SDLGCC patch 2: pointer to functions now generated properly, part 01/01

Patch-to: sdlgcc: Volume 3, Issue 102-103,108

This patch to SDLGCC corrects a bug which prevented pointers to functions in
structures from being properly generated.  There remains a bug in handling
general address constructs, but I'll fix that one when I need it.  Apply all
previous patches before applying this one.

Good Luck.
