TEA_LOAD_TKCONFIG

#-----------------------------------------------------------------------
# Handle the --prefix=... option by defaulting to what Tcl gave.
# Must be called after TEA_LOAD_TCLCONFIG and before TEA_SETUP_COMPILER.
#-----------------------------------------------------------------------

TEA_PREFIX

#-----------------------------------------------------------------------
# Standard compiler checks.
# This sets up CC by using the CC env var, or looks for gcc otherwise.
# This also calls AC_PROG_CC, AC_PROG_INSTALL and a few others to create
# the basic setup necessary to compile executables.
#-----------------------------------------------------------------------

TEA_SETUP_COMPILER

#--------------------------------------------------------------------
# __CHANGE__
# Choose which headers you need.  Extension authors should try very
# hard to only rely on the Tcl public header files.  Internal headers
# contain private data structures and are subject to change without
# notice.
# This MUST be called after TEA_LOAD_TCLCONFIG / TEA_LOAD_TKCONFIG
#--------------------------------------------------------------------

# This module is special. On windows it requires access to the
# internal headers of Tk and thus tcl to implement its functionality
# (TkWinReleaseDrawableDC).

# Check whether --enable-threads or --disable-threads was given.
# So far only Tcl responds to this one.
#--------------------------------------------------------------------

TEA_ENABLE_THREADS

#--------------------------------------------------------------------
# The statement below defines a collection of symbols related to
# building as a shared library instead of a static library.
#--------------------------------------------------------------------

TEA_ENABLE_SHARED

#--------------------------------------------------------------------
# This macro figures out what flags to use with the compiler/linker
# when building shared/static debug/optimized objects.  This information
# can be taken from the tclConfig.sh file, but this figures it all out.
#--------------------------------------------------------------------

TEA_CONFIG_CFLAGS

#--------------------------------------------------------------------
# Set the default compiler switches based on the --enable-symbols option.
#--------------------------------------------------------------------

TEA_ENABLE_SYMBOLS

#--------------------------------------------------------------------
# For Unix/Tk builds, make sure that the X libraries/headers are found.
# This must be called after TEA_CONFIG_CFLAGS as it adjusts LIBS.
#--------------------------------------------------------------------

TEA_PATH_X

#-----------------------------------------------------------------------
# All relevant packages are configuration subdirectories.
#-----------------------------------------------------------------------

# I. Support

# Remove all arguments after the command name. Without doing that we
# might transmit something like 'gcc -pipe' down to the sub
# configure's, and they may hang in 'which gcc -pipe' (platform
# dependent. So far only seen for Linux).
