hdf5/bin/trace
Dana Robinson 14bc39bcb5 Updated bin/trace to emit errors and reordered autogen.sh processing
so that script failures leave the library in a non-compilable state,
making it harder to ignore errors.

# 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.
