Installing GCC Configuration_-CSDN
· Installing GCC Configuration. Like most GNU software GCC must be configured before it can be built. This document describes the recommended configuration procedure for both native and cross targets. We use srcdir to refer to the toplevel source directory for GCC we use objdir to refer to the toplevel build/object directory.

85678-fno-common should be defaultGCC the GNU
gcc supports this if "-fcommon" is enabled which is the default on most targets. But it is contrary to the C (and C ) standards that say there shall be exactly /one/ definition of each object. And it is very easy to have errors in code by accidentally having duplicate names in different files (if the programmer has not used "static") perhaps even of different types.

ocaml compile with -fcommon to support gcc 10 by avsm
· -fcommon has been supported from gcc 4.4 upwards which is a reasonable base default. This patch skips a few compiler variants that already have patches such as termux and the bucklescript variants. Those can deal with gcc10 on their own if they still need it.

Compile old C code (on Linux) that throws errors (Multiply
· The default of pre-10 gcc used to be -fcommon but that has been changed to -fno-common in gcc 10. From the gcc 10 release notes GCC now defaults to -fno-common. As a result global variable accesses are more efficient on various targets. In C global variables with multiple tentative definitions now result in linker errors.
