Build error in tseries.c on OS X 10.8.2

[fonnesbeck]

Just updated OS X to 10.8.2 and Xcode to 4.5. Building pandas (commit 1e68fd9) now fails with an undeclared variable error in some cython code.

stale .c file?

def monthrange(int64_t year, int64_t month):
    cdef:
        int64_t days
        int64_t day_of_week

    if month < 1 or month > 12:
        raise ValueError("bad month number 0; must be 1-12")

    days = days_per_month_table[is_leapyear(year)][month-1]

    return (dayofweek(year, month, 1), days)

Thanks. Flushed all the .c files out for pandas/src and all is well. Odd that it just happened now.

Actually, it looks like the depends list for that Cython extension needs to get expanded-- a C header file was edited recently which is what broke your build.
