The Seed7 language, if you were to build it from C sources, comes with
nearly 20 different makefiles for different compilers and platforms.
There's also a configure program which creates and runs some 100
different test programs to collate information about the C
implementation, resulting in a configuration header file describing the
environment.
Since Seed7 also uses C as a target language, I can't remember if that
config file was for the compiler, or compiling the generated C
intermediates, or both.
Use C as a target is not that simple!
When I used to target C, I produced a single C source for the entire
program, but there were three versions, since it didn't have conditional
elements:
* For Windows
* For Linux
* For a Neutral OS (runs on either but with limitations)
I think also the code assumed a 64-bit implementation; a 32-bit target,
if I was to still bother with it, would need separate versions.
I used to try and support half a dozen C compilers, which was hard as
they all had different limitations. Now I support only tcc and gcc.
No special options are required (other than ones like -O2 and -o for
gcc), and no special extensions (a few things expected to be in C99 like
anonymous structs and unions).
The main limitation of tcc (a significant one for me) is that it doesn't
support '$' in identifiers; most C compilers do. Which means taking
account of that in code generators.
