a small amount of unused stuff (by the bmakefiles to follow), but it isn't much and seems harmless enough.

# This is a shell-script that figures out various things about a
|
|
# system, and writes (to stdout) a C-style include files with
|
|
# suitable definitions, including all the standard Posix types.
|
|
# It works by compiling various test programs -- some are run through
|
|
# the C pre-processor, and the output examined.
|
|
# The test programs are only compiled, not executed, so the script
|
|
# should even if you're cross-compiling.
|
|
# It uses $CC (which defaults to cc) to compile C programs (extension .c),
|
|
# and $CXX (which defaults to gcc) to compile C++ programs (extension .C).
|
|
# The shell-script is written for libg++.a.
|
|
|
|
# Usage: gen-params [NAME1=name1 ...]
|
|
# - where an assignment (such as size_t="unsigned int" means to
|
|
# use that value, instead of trying to figure it out.
