The eCos modGPL is GPL compatible. See
http://ecos.sourceware.org/license-overview.html and
http://www.gnu.org/philosophy/license-list.html#GPLCompatibleLicenses
The last part of the modification eCos applies to GPL is:
This exception does not invalidate any other reasons why a
work based on this file might be covered by the GNU General
Public License.
Linking to code which is GPL'd would be one such "any other reasons"
which would require you to distribute eCos as GPL.
What you want to do is O.K., but IANAL!
