Hi All,
this is just an info for other mantainers and users
on gcc-4.3.2-2.

As reported by David announcment
http://cygwin.com/ml/cygwin/2009-03/msg00378.html
the current standard is "linked statically against libgcc".

I found a case where=20

   CC=3D"gcc-4 -shared-libgcc"

is absolutely needed and=20

   CC=3Dgcc-4=20

does not work.

With hdf5-1.6.8 in both cases the compilation is fine
but during "make check" if CC=3Dgcc-4 is used
the test of I/O drivers crashes very bad and moreover=20
it cripples the underlying cygwin1.dll.
I need a restart to be able to perform again the test
with any version.=20

I suppose it is an exception handling issues, and it=20
applies to both 1.5 and 1.7 cygwin versions.

Currently I am rebuilding all my cygwin-1.7=20
packages with CC=3D"gcc-4 -shared-libgcc"
and I have not yet found problems.


Regards
Marco
