Indeed it is, but the code uses strcasestr and I couldn't find any 
indication which standard that function is part of.

Adding that function to compat/ probably is the way to go, but the whole 
compat mechanism doesn't work here. It's like if compat/Makefile.local 
was not included in the top-level makefile, notmuch_compat_srcs is empty 
there. Any ideas how to debug that?
