ompiler\include\stdint.h(39): fatal error C1083: Cannot open include file: '../../vc/include/stdint.h': No such file or directory
This occurs with both XE2017u4 and XE2018 beta.
If the CL build step is run in the VS2017 developer prompt, the resulting .obj has no problem linking in the Intel cmd window for either VS2015 or 2017.
The CL build failure occurs only when VS2017 is set under the ICL cmd window. ICL doesn't have a problem.
Warnings about redefinition of HUGE_VAL.. occur both in the working and non-working cases. They show that math.h is being processed successfully although with warnings, along the same include path. Those redefinitions are present in the ICL math.h.
There may be something wrong with my setup, but I don't see it, other than the strange comment about looking for a posix style include path even though running under DOS style cmd window. That is actually the way the paths are written in the ICL installation of stdint.h.
