Subject: MinGW needs an extra symbol _WIN32_IE defined to a particular value before
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/8f5f26d24e18e267dd56e8c0b7d856027f63e41c?hp=62ddb51e0424dd4bd1098b024f2427959aefc729

MinGW needs an extra symbol _WIN32_IE defined to a particular value before
it'll let you see an identifier (SHGFP_TYPE_CURRENT) referenced since r7082.
(Actually, you need a pretty recent w32api before it's there at all.)

Morally, this should be defined for all toolchains, not just MinGW/Cygwin, but  I'll leave that to people who have those toolchains.

Also add some other comments on our use of this API (since it's a horrible one
that I suspect will come back and haunt us...)
