[Mingw-cross-env-list] guile 2.0.11

[Kai-Martin Knaak]

In an effort to cross compile the electronics application geda I need to
bump guile. The geda utils depend on guile version > 2.0 .  So this is
what I did:

1) git cloned the current master branch of MXE

2) build the environment with
make gcc

3) bumped the version in guile.mk :

/----------------
PKG             := guile
#$(PKG)_IGNORE   := 2%
$(PKG)_VERSION  := 2.0.11
$(PKG)_CHECKSUM := ae86544b39048a160f4db1c0653a79b40b6c1ee6
(...)
define $(PKG)_BUILD
(...)
    '$(TARGET)-gcc' \
        -W -Wall -disable-Werror -ansi -pedantic \
        '$(2).c' -o '$(PREFIX)/$(TARGET)/bin/test-guile.exe' \
        `'$(TARGET)-pkg-config' guile-$(call SHORT_PKG_VERSION,$(PKG))
--cflags --libs` \ -DGUILE_MAJOR_MINOR=\"$(call
SHORT_PKG_VERSION,$(PKG))\" endef
\----------------

In addition I added "-disable-Werror". The original "-Werror" flag made
the build process exit at the config stage. It complained about the
type "long long", which allegedly is not supported in c90.

With this flag warnings are ignored and the build declares success.

However, I get immediate segfault if I start the resulting guile.exe with
wine32. This should bring up a simple command line environment. Instead,
I get:
/----------------------------
/usr/local/src/minipack/result/bin$ wine32 guile.exe

        00000021    0
        0000002e    0 <==
\------------------------------

I am lost here. How would I debug this? Any lead? Would gdb be an option?
What would be the most likely culprit?
