Issues with building gcc trunk with ada on cygwin

[Christian Joensson <christian dot joensson at gmail dot com>]

I have an issue with building gcc trunk, current and since quite a while.

There seems to me to be quite some missing includes while building
stage 3 compared with stage 2.

For example, the adadecode.c comile in stage 2 for me looks like this:

make[5]: Entering directory
`/usr/local/src/trunk/objdir.withada-java/gcc/ada/rts'

while the stage1 compile looks liike this:

/usr/local/src/trunk/objdir.withada-java/../gcc/gcc/ada/adadecode.c -o
ada/adadecode.o

the compile error I get in stage 2 is resolved adding
-I/usr/local/src/trunk/gcc/gcc/ as include, there, and only there, is
the missing include file config/i386/xm-cygwin.h...

Now, are there anyones here that recognise the issue and perhaps have
an idea of how to address it?
