# This is a specially modified version of the Makefile that will build
# Fossil on Mac OSX Jaguar (10.2) circa 2002.  This Makefile is used for
# testing on an old PPC iBook.  The use of this old platform helps to verify

#
#     make -f Makefile.osx-jaguar

# About Fossil

Fossil is a distributed version control system that has been widely
used since 2007.  Fossil was originally designed to support the
[SQLite](https://sqlite.org) project but has been adopted by many other
projects as well.

Fossil is self-hosting at <https://fossil-scm.org>.

If you are reading this on GitHub, then you are looking at a Git mirror
of the self-hosting Fossil repository.  The purpose of that mirror is to
test and exercise Fossil's ability to export a Git mirror.  Nobody much
uses the GitHub mirror, except to verify that the mirror logic works.  If
you want to know more about Fossil, visit the official self-hosting site
linked above.

    "requester" object per connection attempt, for connections to the
    same back-end, using an instance configured for that back-end
    can simplify usage. This class is designed so that the actual
    connection-related details (i.e. _how_ it connects to the
    back-end) may be re-implemented to use a client's preferred
    connection mechanism (e.g. jQuery).

    The optional opt parameter may be an object with any (or all) of
    the properties documented for WhAjaj.Connector.options.ajax.
    Properties set here (or later via modification of the "options"
    property of this object) will be used in calls to
    WhAjaj.Connector.sendRequest(), and these override (normally) any
    options set in WhAjaj.Connector.options.ajax. Note that
    WhAjaj.Connector.sendRequest() _also_ takes an options object,
    and ones passed there will override, for purposes of that one

README.autosetup created by autosetup v0.6.9

This is the autosetup directory for a local install of autosetup.
It contains autosetup, support files and loadable modules.

*.tcl files in this directory are optional modules which
can be loaded with the 'use' directive.

*.auto files in this directory are auto-loaded.

#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.

# @cctest ?settings?
#
# Low level C/C++ compiler checker. Compiles and or links a small C program
# according to the arguments and returns 1 if OK, or 0 if not.
#
# Supported settings are:
#
## -cflags cflags      A list of flags to pass to the compiler
## -includes list      A list of includes, e.g. {stdlib.h stdio.h}
## -declare code       Code to declare before main()
## -link 1             Don't just compile, link too
## -lang c|c++         Use the C (default) or C++ compiler
## -libs liblist       List of libraries to link, e.g. {-ldl -lm}
## -code code          Code to compile in the body of main()
## -source code        Compile a complete program. Ignore -includes, -declare and -code
## -sourcefile file    Shorthand for -source [readfile [get-define srcdir]/$file]
## -nooutput 1         Treat any compiler output (e.g. a warning) as an error
#
# Unless '-source' or '-sourcefile' is specified, the C program looks like:
#
## #include <firstinclude>   /* same for remaining includes in the list */
##
## declare-code              /* any code in -declare, verbatim */
##
## int main(void) {

##   return 0;
