Zhang Xianyi 5f0117385e Refs #154. Fixed a SEGFAULT bug of dgemv_t when m is very large. 
It overflowed the internal buffer. Thus, we split vector x into blocks when m is very large.

Thank @wangqian for this patch.

Zhang Xianyi 2573311308 refs #140. Fixed zdot incompatibility ABI issue with GCC 4.7 on Win 32. 
GCC 4.7 uses MSVC ABI on Win 32. This means the caller pops the hidden pointer for returning
aggregate structures larger than 8 bytes.
