2002-09-18 Mumit Khan <khan@nanotech.wisc.edu>
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.
