My test was done with DJGPP development version (2.04) only. It has stdint.h,
but it was recognized by configure as unusable due to bug unrelated to GCC
itself. After fixing this problem locally libstdc++-v3 builds OK for DJGPP
v2.04 (only tested cross-native build from Linux)

Stable version DJGPP v2.03 does not have stdint.h

As the result I agree with the suggestion in comment 3 to completely disable
random.cc when _GLIBCXX_USE_C99_STDINT_TR1 is not defined

Maybe it would be nice to use #error in header file to inform the user that
this feature is not supported for target system (nicer than to get linker error
later)
