[Bug bootstrap/14344] New: [3.3.3 Regression] MinGW Bootstrap Failure

["stl at caltech dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

MinGW gcc 3.3.3 fails to bootstrap.  This is a regression because I have been 
able to bootstrap previous 3.3.x releases.

I am working with MSYS (not Cygwin) and I am using the MinGW patches on top of 
the FSF sources. I have flex and bison. I work in /c/temp/gcc/build with the 
sources in /c/temp/gcc/src and the destination /c/temp/gcc/dest . I execute:

../src/configure --prefix=/c/temp/gcc/dest --enable-languages=c,c++ --enable-
sjlj-exceptions --enable-threads=win32 --disable-win32-registry --disable-
shared --without-newlib --disable-nls --disable-debug

Which succeeds.  Then I execute:

make "CFLAGS=-O3 -fomit-frame-pointer -ffast-math" "LDFLAGS=-s -Wl,--
stack=0x00800000" bootstrap

This fails with:

I see that cygming.h does not exist in that location. I have verified that the 
file is not present in the plain FSF gcc 3.3.3 sources (i.e. the MinGW patches 
do not remove it).

What's going on?
