make fails with gmime-2.6.4

[Mark Foxwell]

Hi,

My distro, Arch Linux, has gmime-2.6.4 in their testing repo. Notmuch
(from git master branch) fails to build with the following output:

CC -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector
--param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 command-line-arguments.o
CC -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector
--param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 debugger.o
In file included from debugger.c:21:0:
notmuch-client.h:72:5: error: unknown type name ‘GMimeSignatureValidity’
notmuch-client.h:86:5: error: unknown type name ‘GMimeCipherContext’

‘GMimeSignatureValidity’
notmuch-client.h:322:3: error: unknown type name ‘GMimeCipherContext’
make: *** [debugger.o] Error 1

Not sure if you're aware of this? 

Kind Regards,

Mark
