[PULL] linuxdoc, other build fixes

[Yaakov (Cygwin/X)]

Keith,

Please note that the "dmx: Ignore linuxdoc generated docs" patch will 
force those running 'make dist' (primarily you and whot) to have a 
working linuxdoc installation.  If that requirement is not desirable, 
then adding just the .gitignore part of that patch will still be helpful 
for those working from git.

The following changes since commit b557571dbff3d9a615e03cad904d46b8af9153a0:
