[Gcl-devel] help fixing edit_double, failure to print 1d-6 for gcl-2.6.8

[David Billinghurst]

The current maxima 5.31.2 release for windows is built with cvs 
gcl-2.6.8pre from 2013-01-01.  The previous release used gcl-2.6.8, but 
this has a bug where 1e-6 is printed as 0.0.

I tried backporting Camm's patch to 2.6.20pre
http://git.savannah.gnu.org/cgit/gcl.git/commit/?h=Version_2_6_10pre&id=b25201deb6e0303e92adb105a610f367745032d4
but the resulting maxima has many testsuite failures.

I have identified the patch to 2.6.8pre that introduced the bug
http://cvs.savannah.gnu.org/viewvc/gcl/o/print.d?root=gcl&r1=1.15.4.1.2.2.12.1.2.1.2.1&r2=1.15.4.1.2.2.12.1.2.1.2.2&pathrev=Version_2_6_8pre

I would like to fix 2.6.8 and get a 2.6.8-1 (or whatever) release so 
that maxima is can again be built with a released version of gcl.  
Unfortunately is isn't immediately obvious to me what the fix is.  I can 
probably work it out, but it is easier to ask :-).
