[Vm-dev] Failing win64x64 builds - undeclared identifier 'PATH_MAX'

[Ben Coman]

Just to note that builds...
* Environment: FLAVOR=squeak.stack.spur, ARCH=win64x64,
CYG_ROOT=C:\cygwin64, CYG_SETUP=setup-x86_64.exe, MINGW_ARCH=x86_64
* Environment: FLAVOR=pharo.stack.spur, ARCH=win64x64,
CYG_ROOT=C:\cygwin64, CYG_SETUP=setup-x86_64.exe, MINGW_ARCH=x86_64
are currently failing due to...
   ../../platforms/Cross/plugins/B3DAcceleratorPlugin/sqOpenGLRenderer.c:85:17:
       error: use of undeclared identifier 'PATH_MAX'
       char fileName[PATH_MAX+1];

The change from imageNameSize() to PATH_MAX seems to be from 11 days ago per...
https://ci.appveyor.com/project/OpenSmalltalk/vm/build/1.0.637
"Add the B3DAcceleratorPlugin (OpenGL interface) to the 32-bit Mac build"
