In general you will get much better help if you indentify the actual
library you're trying to compile, or paste actual code, or better yet, a
simple standalone testcase.

The tm_gmtoff member of struct tm is not a part of any standard.  It's
present on some BSD systems and glibc, but it's not required by
posix/ISO standards.  Whatever code you're compiling needs to be
modified because it's not portable.
