Added basic Cygwin support. * win/tcl.m4 (SC_PATH_TCLCONFIG): Support one-tree build. (SC_PATH_TKCONFIG): Likewise. (SC_PROG_TCLSH): Likewise. (SC_CONFIG_CFLAGS): Assume real Cygwin port and remove -mno-cygwin flags. Add -mwin32 to extra_cflags and extra_ldflags. Remove ``-e _WinMain@16'' from LDFLAGS_WINDOW. * win/configure: Regenerate. * win/tkWinPort.h (tchar.h): Do not include on Cygwin. (_T): Define for Cygwin. * win/winMain.c (main): Conditionally define.

+ # ORIGINAL COMMENT:
# We need to pass -e _WinMain@16 so that ld will use
# WinMain() instead of main() as the entry point. We can't
# use autoconf to check for this case since it would need
# to run an executable and that does not work when
# cross compiling. Remove this -e workaround once we
# require a gcc that does not have this bug.
