Um. Is it possible that you redefined XLOG_SEG_SIZE or used --with-wal-
segsize=SEGSIZE?

The default is still:
andres@alap2:~/src/postgresql$ grep XLOG_SEG_SIZE src/include/pg_config.h
/* XLOG_SEG_SIZE is the size of a single WAL file. This must be a power of 2
   XLOG_BLCKSZ). Changing XLOG_SEG_SIZE requires an initdb. */
#define XLOG_SEG_SIZE (16 * 1024 * 1024)
