16 * NOTES
946da5994c01 updated for version 7.0006
vimboss
parents:
diff changeset
17 * 1. Memory, allocated with scheme_malloc*, need not to be freed explicitly,
946da5994c01 updated for version 7.0006
vimboss
parents:
diff changeset
18 * garbage collector will do it self
946da5994c01 updated for version 7.0006
vimboss
parents:
diff changeset
19 * 2. Requires at least NORMAL features. I can't imagine why one may want
946da5994c01 updated for version 7.0006
vimboss
parents:
diff changeset
20 * to build with SMALL or TINY features but with MzScheme interface.
946da5994c01 updated for version 7.0006
vimboss
parents:

21 * 3. I don't use K&R-style functions. Anyway, MzScheme headers are ANSI.
