Subject: Fix MSVC warning on streampos to size_t conversion
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=8751b18cf0b5ddb9d7549a465444d5ace215a097;hp=2608b9249d9c25a699c8db8725e35bd4ec0b65ab

Fix MSVC warning on streampos to size_t conversion

Fix this warning with MSVC 64 bits:

warning C4244: '=' : conversion from 'std::streampos' to 'size_t',
possible loss of data

Point is that std::streampos could be negative, while size_t
is always non-negative.

No functional change.
