Problems Compiling Emacs on Windows

[Ulrich Dirr]

I've downloaded the latest Cygwin. For comparison I also installed
MinGW. Then I downloaded the cvs emacs repository.

I read the readme/install etc. files. According to these files I should
change to subdir emacs/nt and run a batch file configure.bat (but why
use a batch file first on a win command prompt and then a shell for
compiling?).

As written in INSTALL-CVS I've invoked the makefile via 'make
bootstrap'. But failed. No idea. I tried the command within a win2k
command prompt, with MinGW/MSYS, and finally with bash from Cygwin. All
three are working quiet a while and all three are stopping with the same
error message like below:

C:/bin/msys/1.0/mingw/include/setjmp.h:63: conflicting types for
`longjmp'
w32fns.c:10488: previous declaration of `longjmp'
w32fns.c:11019: parse error before "jpeg_resync_to_restart_wrapper"
w32fns.c:11020: parse error before "j_decompress_ptr"
w32fns.c:11020: warning: data definition has no type or storage class
w32fns.c:11022: parse error before '{' token
w32fns.c:11047: field `pub' has incomplete type
w32fns.c:11049: confused by earlier errors, bailing out
make[2]: *** [oo-spd/i386/w32fns.o] Error 1
make[2]: Leaving directory `/c/usr/uli/emacs/src'
make[1]: *** [bootstrap-temacs] Error 2
make[1]: Leaving directory `/c/usr/uli/emacs/src'
make: *** [bootstrap-gmake] Error 2

I have no idea what I did wrong nor how I can correct it. Maybe my
environment isn't setup correctly?

Please help.
