Cygwin Package mingw64-x86_64-gettext 0.22 mingw sh ==dash

[Brian Inglis]

Hi Bruno,

Building Cygwin Package mingw gettext 0.22 got a problem running configure with 
sh == dash, in latest gettext 0.22 gettext-runtime/intl/configure and elsewhere 
handling localedir converting to localedir_c/localedir_c_make all containing 
Windows paths, especially under Cygwin, as you will see, demonstrated in the 
attached script and log, explained in the attached patch for configure.

Under sh == dash echo \0## \b \t \n \v \f \c are escapes,
also \c as in \cygwin in Windows path suppresses output as EoL,
so Windows paths containing \c as in \cygwin are truncated:
use printf "%s" "$gl" instead of echo "$gl"!

I have not yet found where this transformation is generated from (some m4?), so 
any pointers would help.
Other workarounds may be needed under other shells, depending on echo escapes 
and printf availability, perhaps a $gl_safe_echo or $SAFE_ECHO?
