OK to apply to HEAD? Also branch-1-10?
I'm wondering a bit whether we risk clashes wrt. file name extensions
here. OpenOffice uses extensions matching .sx? but AFAIK no plain .sx
(yet). Does anybody know whether w32 has a default action for these?
Searching the net, I found these programs using files matching *.sx:
SAS Stat Studio Program Source Code
Stradx
None of these look like more likely candidates for Automake.
Cheers,
Ralf
