[Ecls-list] MinGW build

[francogrex at mail.com]

ok now the latest cvs download works well with MinGW/msys but did you 
test --with-dffi ?

./configure --enable-threads --enable-unicode --with-dffi 
--target=i686-pc-mingw32 --build=i686-pc-mingw32 --host=i686-pc-mingw32
...
checking for ffi_call in -lffi... yes
checking for ffi/ffi.h... no
checking for ffi.h... no
configure: WARNING: unable to find header file ffi.h; disabling dynamic 
FFI
...

This is not correct as libffi is installed and ffi.h is in the path. 
There is probably some error in the config file.
These days almost all libraries use cffi and dffi is needed for that.
