[Tinycc-devel] [PATCH] tcc_malloc fix

[Rogelio M. Serrano Jr.]

This is a patch to fix the "memory full" failure when using the uclibc
compiled tcc. This is due to the difference in behaviour between the glibc
and uclibc malloc. Uclibc returns a NULL when you call malloc with size =
0 while glibc does not. Allocating zero bytes should fail right? Glibc is
just strange.
