[notmuch] [PATCH] Solaris doesn't have 'struct dirent::d_type'

[Tomas Carnecky]

Use stat(2) instead.

There is a second issue that prevents notmuch from working on Solaris:
the getpwuid_r() prototype doesn't have the last argument. But that can
be easily worked around by setting -D_POSIX_PTHREAD_SEMANTICS on the
compiler commandline. Do you want to use uname to detect the platform
and define platform-specific code or can I unconditionally add that
define to CFLAGS?
