Small bug in gpgme configure script or Makefile ?!?

[bsmaillist at skynet.be]

When I try to configure && make gpgme 0.3.12 from source from the following 
directory:
/data/tmp/GnuPG 1.9/gpgme-0.3.12

I get this error from make

(cd .libs/libgpgme.lax/libassuan.al && ar x /data/tmp/GnuPG 
1.9/gpgme-0.3.12/gpgme/../assuan/.libs/libassuan.al)
ar: /data/tmp/GnuPG: No such file or directory
make[3]: *** [libgpgme.la] Error 9
make[3]: Leaving directory `/data/tmp/GnuPG 1.9/gpgme-0.3.12/gpgme'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/data/tmp/GnuPG 1.9/gpgme-0.3.12/gpgme'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/data/tmp/GnuPG 1.9/gpgme-0.3.12'
make: *** [all] Error 2


It seems that the Makefile doesn't like the path with the source code to 
contain a directory name with a blank. It works fine when I change the 
directory from
/data/tmp/GnuPG 1.9/gpgme-0.3.12
to
/data/tmp/GnuPG/gpgme-0.3.12

I noticed the same problem with another component of the GnuPG software  
collection. It's probably just a problem with using quotes the wrong way in 
the autoconf or automake input files.
