This is due to incorrect creation of dependency files:
both compilers do not escape spaces in paths.
As of version 1.21.22 of lcc, it is announced that
this bug will be corrected in future versions.
Test 132 was a template for such idea; it has been also
extended to react not only to icc, but to lcc too.

Fixes the bug with flat layout and identical target names in subprojects.
Without this change directories are not created with subproject prefix
and they can collide.
Remove dead makedirs code in Backend.__init__(), during initialization
of backend build.targets is empty. Create output directories in
Vs2010Backend.generate_projects() instead.
Also use double blank line in run_unittests.py according to
https://www.python.org/dev/peps/pep-0008/#blank-lines.
Former test is extremely hard to follow,
target names are inconsistent with directory names,
test case mixes up 2 separate testing scenarios,
names are meaningless. In order to fix this
provides comments what each command is doing and why,
renamed targets into descriptive and longer names,
made names consistent with contents so that it is easier
to follow test logic without looking up source code.
The documentation doesn't require it and the interpreter code works around the
possibility of it being None. The ninja backend code however fails with
File "/home/whot/code/meson/mesonbuild/backend/ninjabackend.py", line 796, in generate_data_install
dstabs = os.path.join(subdir or None, plain_f)
File "/usr/lib64/python3.6/posixpath.py", line 78, in join
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not NoneType
If install_dir is missing, default to datadir/projectname
Since PR #2884, this is failing with an exception
Keep the behaviour we have had since PR #1810 (0.41.0), that ordering
comparisons of different types fail with an InterpreterException.
Also warn about equality comparisons of different types, which will one day
become an error, as per PR #2884.
Currently only not found deps implicitly pulled from a Library object
are ignored. We should also ignore not found deps passed directly to
generate() method.
This makes the unit testing more complicated because libfoo pkgconfig
dependency cannot be found when generated from the within the same
meson.build.
