another problem building maxima on cygwin

[Dima Pasechnik]

Having another go at building Sage on Cygwin, I get, somewhere very near the end of building Maxima spkg, the following:

.......

cp: cannot stat `maxima.fasb': No such file or directory

***********************************************************

Failed to install maxima.fasb as a library

----------------------------

the command responsible for this seems to be

(asdf:make-build :maxima :type :fasl :move-here ".")

invoked from spkg-install.

and it certainly works anywhere else. 

The parameter 'move-here' does not seem to be documented anywhere...

Is it due to usual Cygwin/windows misnaming (I see in src/binary-ecl/ file maxima.exe) ?

[Dima Pasechnik]

by running ecl stand-alone on the maxima spkg, I can confirm that the error comes from 

(asdf:make-build :maxima :type :fasl :move-here ".")

Unfortunately I cannot find any information on how to use the ecl's debugger.

Any pointers much appreciated.

By the way,

In maxima.asd I see plenty of :pathname "", and the error is

;;; Loading "/home/Dima/sage-4.7.2/spkg/build/maxima-5.23.2.p0/src/src/maxima.asd"

; Registering #<system :MAXIMA> as MAXIMA

An error occurred during initialization:

In function PATHNAME, the value of the only argument is

  NIL

which is not of the expected type (OR FILE-STREAM STRING PATHNAME).

So somehow it might be that due to some LF/CR weirdness, "" cannot be an argument to pathname

(*** my pure speculation***)

I just checked, and saw that under Sage's ECL lisp (i.e. sage -lisp),

(pathname "")

produces an error (illegal seek) on Cygwin,

while on MacOSX and Linux it's perfectly OK.

I got this same error trying out some more recent Maxima packages as
well.
