Configure feature Description: Added 'make trace' target. Solution: Added tracing to 1.7. This was done automatically in 1.6, but left out of 1.7 until now (oops!). Tracing in 1.7 only happens manually, when the user types 'make trace.' Tracing automatically requires more framework than it's worth. I also fixed a couple of tracing bugs and ran trace. Platforms tested: mir, sleipnir, modi4 Misc. update:

# A map from type name to type letter. We use this map for two reasons:
|
|
# 1. We want the debugging stuff in the source code to be as unobtrusive as
|
|
# possible, which means as compact as possible.
|
|
# 2. It's easier (faster) to parse these one and two-letter types in the C
|
|
# functions that display debugging results.
|
|
#
|
|
# All type strings are one or two characters. One-character strings
|
|
# are always lower case and should be used for common types.
|
|
# Two-character strings begin with an upper-case letter which is
|
|
# usually the same as the package name.
