+- struct/union/enum definitions in nested scopes (see also Debian bug #770657)
+- __STDC_IEC_559__: float f(void) { static float x = 0.0 / 0.0; return x; }
+- memory may be leaked after errors (longjmp).

+Portability:
+
+- it is assumed that int is 32-bit and sizeof(int) == 4
+- int is used when host or target size_t would make more sense
+- TCC handles target floating-point (fp) values using the host's fp
+  arithmetic, which is simple and fast but may lead to exceptions
+  and inaccuracy and wrong representations when cross-compiling

+Linking:

+- static linking (-static) does not work
