fixing first. The easiest way to do this and avoid future conflicts
is to run the following command in this (emacs/nt) directory:

cvs update -kb

If you build Emacs on Windows 9X or ME, not on Windows 2K/XP or
Windows NT, we suggest to install the Cygwin port of Bash.
- Please see http://www.mingw.org for pointers to GCC/Mingw and binaries.

For reference, here is a list of which builds of GNU make are known
to work or not, and whether they work in the presence and/or absence
cygwin compiled make 3.78.1: fails[5] fails[2, 5]
cygwin compiled make 3.79.1: fails[3, 5] fails[2?, 5]
mingw32 compiled make 3.79.1: okay okay
+ mingw32 compiled make 3.80: okay unknown[6]
Notes:
[4] may fail on Windows 9X and Windows ME; if so, install Bash.
[5] fails when building leim due to the use of cygwin style paths.
May work if building emacs without leim.
+ [6] please report if you try this combination.

surpressed because of limitations in the Windows 9x command.com shell.
+ You are encouraged to look at the file config.log which shows details
+ for failed tests, after configure.bat finishes. Any unexplained failure
+ should be investigated and perhaps reported as a bug (see the section
+ about reporting bugs in the file README in this directory and in the
+ Emacs manual).

* Optional image library support
In addition to its "native" image formats (pbm and xbm), Emacs can
configure script is run. This can be setup using environment
variables, or by specifying --cflags -I... options on the command-line
to configure.bat. The configure script will report whether it was
- able to detect the headers.

+ incorrect, please look for details in the file config.log: it will show
+ the failed test programs and compiler error messages that should explain
+ what is wrong. (Usually, any such failures happen because some headers
+ are missing due to bad packaging of the image support libraries.)
To use the external image support, the DLLs implementing the
- functionality must be found when Emacs is started, either on the PATH,
- or in the same directory as emacs.exe. Failure to find a library is
- not an error; the associated image format will simply be unavailable.

+ unavailable. Note that once Emacs has determined that a library can
+ not be found, there's no way to force it to try again, other than
+ restarting. See the variable `image-library-alist' to configure the
+ expected names of the libraries.
Some image libraries have dependencies on one another, or on zlib.
For example, tiff support depends on the jpeg library. If you did not

Binaries for the image libraries (among many others) can be found at
- GnuWin32 (http://gnuwin32.sourceforge.net). These are built with
- MinGW, and so are very compatible with GCC/MinGW builds of Emacs (like
- the official binary tarballs for Windows). Compatibility with MSVC,
- on the other hand, is still weak and should not be trusted in
- production environments; if you really need an MSVC-compiled Emacs

- we'll be interested on hearing of any such effort).

* Trouble-shooting
The main problems that are likely to be encountered when building
- Emacs stem from using an old version of GCC, or old Mingw or W32 API
+ Emacs stem from using an old version of GCC, or old MinGW or W32 API
headers. Additionally, cygwin ports of GNU make may require the Emacs
source tree to be mounted with text!=binary, because the makefiles
generated by configure.bat necessarily use DOS line endings. Also,
addsection.c relies on. Versions of w32api-xxx.zip from at least
1999-11-18 onwards are okay.
+ When in doubt about correctness of what configure did, look at the file
+ config.log, which shows all the failed test programs and compiler
+ messages associated with the failures. If that doesn't give a clue,
+ please report the problems, together with the relevant fragments from
+ config.log, as bugs.

If configure succeeds, but make fails, install the Cygwin port of
Bash, even if the table above indicates that Emacs should be able to
build without sh.exe. (Some versions of Windows shells are too dumb
