<div>
<pre>A define specified via -D that has two slashes together will be truncated.
Example:
<span class="quote">> echo TFILE > test
> cpp -DTFILE="/some/path//foo/bar" test</span >
# 1 "test"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 338 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "test" 2
/some/path
>
Expected output of the preprocessor should have /some/path//foo/bar.</pre>
