Feature Description: bin/reconfigure now allows users to define the paths to the autotools on their system. bin/reconfigure also runs the trace script when it is invoked. Solution: The autotools are specified using environment variables: AUTOCONF, AUTOMAKE, ACLOCAL, AUTOHEADER, and LIBTOOL_DIR. See bin/reconfigure for the defaults. The version of each of the autotools is checked before they are run, so users can't invoke the wrong version of any autotool. The trace script is run on all the .c files in the src directory when reconfigure is invoked. Ideally, bin/reconfigure should be run when any new function is added to the library, but if the tracing information is out of date the library will still work. The trace script has also been modified to ignore the multi and stdio file drivers (per Quincey's suggestion). Platforms tested: mir, shanti

# 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.
