Summary0001260: remove useless header include in NSString+Utilities.m

this #include <crypt.h> breaks compilation of sogo on OpenBSD with llvm/clang.
the header doesn't exist there, and this is an error with llvm/clang, where it is only a warning with gcc. Even the manual page on Linux crypt(3) says that only this is needed:
#include <unistd.h>

which apparently also exists in the NSString+Utilities.m.

attached patch removes this inclusion.

TagsNo tags attached.

Not sure I understand here. How to remove the warning with gcc if we don't include crypt.h?

NSString+Utilities.m has everything needed for crypt(3).
It doesn't need to include <crypt.h> at all. Since it exists on Linux, there is no warning, and also no harm in including it anyways. However, when using clang to compile SOPE, this ends in an error, because crypt.h doesn't exist. With gcc, this is only a warning about the nonexistent header file.

Simply removing the include statement, will get rid of the warning with gcc, and will allow compile that file with clang.

I hope now its more clear.

With the #include <crypt.h>, I get no warning using gcc. But without it, I get:

So I don't understand why you say "Simply removing the include statement, will get rid of the warning with gcc..." since removing the include does generate a warning!

Sorry, I haven't seen the comment from the 20.06.

The Linux manual page seems about crypt(3) seems to be wrong, so I'm sorry.
I rechecked the manual page, and the source file, the manual page states, the following is needed:

#define _XOPEN_SOURCE 1
#include <unistd.h>

which is there in the source file, and is enough to compile on OpenBSD.
Maybe then just enclosing the inclusion of the crypt.h so it looks like the following would be enough for me:

#ifndef OpenBSD
#include <crypt.h>
