[cygwin] acosf' undeclared (first use here)

[Marco.Herrn@de.gi-de.com]

Hi,

I am trying to build a crosscompiler on cygwin for a sparc-sun-solaris2.7
target.

I configured and installed binutils, then configured gcc (3.2.1, I tried
with 2.95.3, but it had problems with fixincludes).
When doing make I got the error message: "C compiler cannot create
executables"
When doing make I again, I suddenly got a different error message in
libiberty. It said "no rule to make target 'all'".
After searching in google I found, that it would solve the problem to copy
$builddir/sparc-sun-solaris2.7/libiberty to
$builddir/sparc-sun-solaris2.7/sparcv9, running configure and make again,
there.

Then, back in $builddir, I entered 'make' again and got this error message:

There are a lot more.
How do they come? I didn't find a solution in the web.
Help would be very appreciated.
