Hi,
The reason is simple, you basically use 2 compilers:
- tcc for fast development cycle => CC=tcc ./configure; make
- gcc/clang for fast executable speed. => ./configure; make
You ever have played with autoconf, you know how difficult it is to manage compiler differences. This why clang is also mostly compatible with gcc.
If tcc is not, at least, partially compatible with gcc, it means very few source packages will not compile with tcc.
This dramatically lowest the interest of tcc.

Hi there.
My point is "Why should tcc be gcc compatible ?"
Its main aim is to be faster, and "on the run" via #!/usr/bin/tcc.
IMHO, support too many options, and relevant code behind, is anti-productive.

I don't have proper gcc installed (via brew or macports), but I think it would
make sense to first check what gcc does and supports.
On the other hand, if it's only aliases to existing options, possibly which are
enabled only on OSX, then I don't think [m]any would object, and it should
be fairly simple to add and possibly revert later.

Hi maintainers,
As often, Apple reinvent the wheel and makes things differently.
Among other, clang handles shared libs .dylib with a different set of compiler options.
For example, -shared is replaced by –dynamiclib etc…
It means that a ./configure must test if it uses clang or tcc and adapt its compiler options.
Question: with proper #if/#endif do you allow me to handle clang specific options on macos?
FYI I currently see 4/5 options to add (or at least silently drop) to support tcc on macos with a better compatibility with clang.
