# some defaults - you can override these in the platform specific section
# but shouldn't need to for typical *nix toolchains using gcc
#
#   platform        sets the platform (defaults to platform::generic)
#   compile         compile a C source file to an object file
#   version         print the compiler version number
#   ldout           See below
#   link            Command to link one or more object files and create a shared library
#   embed_manifest  Command to embed a manifest into a DLL. (Win-specific)
#   link_debug      See below
#   link_preload    Linker flags to use when dependent libraries are pre-loaded.
#   link_release    See below
#   preproc_define  preprocess C source file (for critcl::cdefines)
#   preproc_enum    ditto
#   tclstubs        cflag to set USE_TCL_STUBS
#   tkstubs         cflag to set USE_TK_STUBS
#   debug_memory    cflag to enable memory debugging
#   debug_symbols   cflag to add symbols to resulting library
#   object          file extension for object files
#   output          flags to set output file
#   strip           cflag to tell linker to strip symbols
#   optimize        cflag to specify optimization level
#   include         cflag to add an include directory
#   noassert        cflag to turn off assertions in Tcl code
#   threadflags     cflags to enable threaded build
#   target          indicates that this is a cross-compile target
#   sharedlibext    the platform shared library extension
#
#   (Support for Fortran)
#   fcompile        compile a Fortran source file to an object file
#   fversion        print the Fortran compiler version number
#   flink           link one or more object files and create a shared library,
#                   if at least one object file comes from Fortran
#   foutput         Fortran flag(s) to set output file
#   finclude        Fortran flag to add an include directory
#   fextra_cflags   Extra C flags for indicating type of Fortran compiler
#
# Any other config options are assumed to refer to Tcl variables and
# these are set when building so they can be used in the Critcl script.
# Typically this is used when defining cross-compile environments to set
# various tcl_platform() values.
#
# You can also set Tcl variables to use in "when" options (see the MacOSX
# section for an example - "set universal ..."). These commands and the
# "when" commands are run in a separate interpreter.
#
# You can also base a build configuration on an existing one by using
# the "copy" option and then specifically setting the config bits that
# you want to change. See win32-x86_64-cl for an example.

# For this architecture gcc does not have compiler switches for change
# between 32/64 results. Rather, gcc has to be built specifically to
# produce either 32 or 64 bit binaries. And if both results are
# wanted, it has to be built and installed twice (in different
# directories).
#
# HP provides precompiled binaries of these two variants at
# http://www.hp.com/go/gcc. Install the desired compiler(s). In case
# of having both ensure that the desired one is first in the PATH.

# NOTE: ldAix was copied from Tcl into a directory in the PATH.

# It might make sense to stuff this file into critcl and then copy it
# out when needed, either into a fixed place, or tempdir. In the
# latter case the link line needs some way of getting the value
# substituted into it. I have no idea of the critcl config allows
