Subject: safer conversion to HANDLER on MinGW-W64
X-Git-Tag: v0.3.0-rc0~74
X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=990f50a73bca9f9fe4f261161b25fb8fb4432e52

safer conversion to HANDLER on MinGW-W64

Assign to "intptr_t", which on some versions of MS-Windows
will widen the variable; then cast to HANDLE.
