I pointed that when try to build other apps with other static library,
libcurl static library without RTLIBCFG=static occurs compile error.

e.g.
https://stackoverflow.com/questions/5839362/why-do-i-get-lnk4098-conflicts-with-use-of-other-libs-when-trying-to-compile-c/5839453#5839453

Is such a static library by default for useful?

As I got the developer's aspect, I use RTLBCFG=static.
