hack the compiler for AP5

comment:1 Changed 17 months ago by Mark Evenson

I don't fully understand the AP5 compilation architecture but it trips up a leaky abstraction in the ABCL compiler which computes SYSTEM::*FASL-UNINTERNED-SYMBOLS* as an alist as it finds uninterned symbols, but then serializes it as a vector when finished.

The patch contains a hack that computes the alist form from the vector form rather than signalling an error.

To truly fix this one would have to understand the Ap5 compilation strategy a bit better, and then adjust the compiler's use of specials.
