[cmake-developers] "Conflicting types for 'cmsysProcess_SetPipeNative'" compiling in MinGW

[vano at mail.mipt.ru]

Completely puzzled by this: a declaration conflicts with... itself?!

$ uname -a
MINGW32_NT-6.1 IVAN-POWERPC 1.0.18(0.48/3/2) 2012-11-21 22:34 i686 Msys

The error part follows, full output is attached.
This happens with both cmake-3.2.0-rc1 and cmake-3.1.3.
