This is a problem with FreeTDS.

The issue is that FreeTDS defines CS_UINT_TYPE, but not CS_BIGINT_TYPE,
and Sybase never defines one without the other.

I'm not convinced this is a "problem" with FreeTDS, and I'm not sure how
to fix it.
FreeTDS doesn't guarantee line-by-line compatibility with Sybase's header
files. The project's header files describe the functions, structures, and
datatypes implemented by the library. If CS_UINT_TYPE but not
CS_BIGINT_TYPE is supported/used/implemented by the library, then only
CS_UINT_TYPE *should* appear in the header file. Anything else would
mislead the developer: the translation unit might compile but fail to
link, or link and not work.
Michael, AIUI DBD::Sybase assumes CS_BIGINT_TYPE upon testing for
CS_UINT_TYPE. Wouldn't it be better to test for CS_BIGINT_TYPE directly?

Agreed - I haven't tested with FreeTDS in quite a while. I just ran a few tests this morning before going to work, and there are a couple of issues that I need to fix, but that will take a few days (at least)
