# Check whether --enable-gcc or --disable-gcc was given.  Do this 
# before AC_PROG_CC and AC_CYGWIN are called so the compiler can 
# be fully tested by built-in autoconf tools.

SC_ENABLE_GCC

#--------------------------------------------------------------------
# Checks to see if the make progeam sets the $MAKE variable.
#--------------------------------------------------------------------

AC_PROG_MAKE_SET

#--------------------------------------------------------------------
# These two macros perform additinal compiler test.
#--------------------------------------------------------------------

AC_CYGWIN

#--------------------------------------------------------------------
# Determines the correct binary file extension (.o, .obj, .exe etc.)
#--------------------------------------------------------------------

AC_OBJEXT

# Check whether --enable-threads or --disable-threads was given.

# The statements below define a collection of symbols related to
# building libtk as a shared library instead of a static library.
#--------------------------------------------------------------------

SC_ENABLE_SHARED

#--------------------------------------------------------------------
# The statements below define a collection of compile flags.  This 
# macro depends on the value of SHARED_BUILD, and should be called
# after SC_ENABLE_SHARED checks the configure switches.
