Guile HEAD on Cygwin-1.7

Guile HEAD on the upcoming Cygwin-1.7 [1]

Good news first: I can't reproduce the infamous "threaded Guile hangs on 
quit" error. (Cygwin has been shipping single-threaded Guile up to now.)

Guile builds with only minor hiccups. I hope these can be fixed before 
the prerelease.

make check shows serious problems. I will investigate further.

* make

** configure and make with the same set of flags

Configuration test passes, make fails. Yes, -Werror.

cc1: warnings being treated as errors
../../libguile/gen-scmconfig.c: In function 'main':
../../libguile/gen-scmconfig.c:427: error: visibility attribute not 
supported in this configuration; ignored
make[2]: *** [gen-scmconfig.o] Error 1


** pass -no-undefined when linking libguile_i18n

Other libs already have this.


** split the #ifdef in libguile/i18n.c line 59

Cygwin has langinfo.h, but not nl_types.h


** wrong path when compiling psyntax-pp.scm

First time only

Making all in module
make[2]: Entering directory `/home/szgyg/src/GIT/guile/=build/module'
/home/szgyg/src/GIT/guile/=build/meta/guile --no-autocompile -s

ERROR: In procedure open-file:
ERROR: No such file or directory: "ice-9/psyntax-pp.scm"
make[2]: *** [ice-9/psyntax-pp.go] Error 1

Subsequent makes use the correct path:

* make check

** -Werror again

** stack overflow

I didn't dive into this yet. Any hint?

** segfault

On one occasion I got
