# Revision 1.13  1998-09-07 18:31:54  peter
#   * fixed $smartlibext -> $staticlibext to fix a 'rm *' :(
#
# Revision 1.12  1998/09/04 17:17:36  pierre
#   + all unknown function ifdef with
#     conditionnal unknown_functions
#     testwin works now, but windowcreate still fails !!
#
# Revision 1.11  1998/09/04 12:33:12  pierre
#   + added SED testing for ascdef.pp and unidef.pp
#   * func.pp ready
#     still some functions missing (commented out for now)
#
# Revision 1.10  1998/09/03 18:17:35  pierre
#   * small improvements in number of found functions
#     all remaining are in func.pp
#
# Revision 1.9  1998/09/03 17:14:54  pierre
#   * most functions found in main DLL's
#     still some missing
#     use 'make dllnames' to get missing names
#
# Revision 1.7  1998/08/21 15:17:01  peter
#   * win32 compiles a bit better, no growheap crash
#
#
