Fix a bug in my last commit, symbol macros that expand to themselves hang.
2011-06-19 Aidan Kehoe <kehoea(a)parhasard.net>
* cl-macs.el (cl-defsubst-expand):
It is occasionally the case that the symbol naming the argument
co-incides with the value that it is replacing; in that case,
using the symbol macro is counterproductive and hangs XEmacs (as
does analogous code in SBCL), so don't.

Reimplement a few GNU functions in terms of their CL counterparts,
for the sake of circularity checking and some speed; add type
checking (used in interpreted code and with low speed and safety
checking) for the sake of revealing incompatibilities when
developing.
* subr.el (remove-hook):
There's no need for flet here, an explicit lambda is enough.

Reimplement a few GNU functions in terms of CL functions, subr.el
2011-06-19 Aidan Kehoe <kehoea(a)parhasard.net>
* cl-macs.el:
* cl-macs.el (assoc-ignore-case, assoc-ignore-representation):
* cl-macs.el (member-ignore-case): New compiler macros.
* subr.el (assoc-ignore-case):
* subr.el (assoc-ignore-representation):
* subr.el (member-ignore-case):
* subr.el (split-path):
* subr.el (delete-dups):
Reimplement a few GNU functions in terms of their CL counterparts,
for the sake of circularity checking and some speed; add type
checking (used in interpreted code and with low speed and safety
checking) for the sake of revealing incompatibilities when
developing.
* subr.el (remove-hook):
There's no need for flet here, an explicit lambda is enough.
