<inttypes.h> now includes <stdint.h> as per the standard

"7.8 Format conversion of integer types <inttypes.h>

1 The header <inttypes.h> includes the header <stdint.h> and extends it with
additional facilities provided by hosted implementations."

You can include <inttypes.h> and do an #if defined on the stdint guard symbol or one of the names from <stdint.h>.  __DECC_VER is the version of the compiler which is independent of the RTL which is somewhat independent of the headers.  I'll make sure the release notes give guidance on how to check for the existence of the new headers.

We are planning an ECO kit which would include a new Math RTL, a new CRTL, and a new DECC$RTLDEF.TLB file.
