I have shared code given to me that compiles on one linux system but not a newer system. The error is uint32_t does not name a type. I realize that this is often fixed by including the <cstdint> or stdint.h. The source code has neither of these includes and I am trying to seek an option that doesn't require modifying due to internal business practices that I can't control. Since it compiles as is on one machine they don't want changes to the source code.
I am not sure if it matters but the older system uses gcc 4.1 while the newer one uses gcc 4.4. I could install different versions of gcc if needed, or add/install library/include files on the newer machine, I have full control of what is on that machine.
What are my options for trying to compile this code on my machine without modifying the source? I can provide other details if needed.

GCC stopped including <stdint.h> some time ago. You now have to include something to get it...

I hope I am not splitting hairs... If you can't modify the source files, then are you allowed to modify the build system or configuration files; or the environment? If so, you can use a force include to insert the file. See Include header files using command line option?
You can modify Makefile to force include stdint.h. If the build system honors CFLAGS or CXXFLAGS, then you can force include it in the flags. You last choice is probably to do something like export CC="gcc -include stdint.h".
The reason I am splitting hairs is OpenSSL and FIPS. The OpenSSL source files for the FIPS Object Module are sequestered and cannot be modified. We have to fallback to modifying supporting scripts and the environment to get some things working as expected.
