I just tried this on several compilers. Ansi C seems to allow calling main(). Ansi C++ seems to always disallow it.

The technique that you describe is a bug. If you were using recursion where you are guaranteed to eventually pop up all the levels that is one thing. But you apparently want to call main() whenever the user feels like it. Each time that you do this, you push another frame on to the stack. Eventually you will overflow your stack. Even if your stack is so large that the program doesn't abort before the box gets rebooted, you have a memory leak.

caca-config(1)						      General Commands Manual						    caca-config(1)

NAME
caca-config - script to get information about the installed version of libcaca SYNOPSIS
caca-config [ --prefix= DIR] [ --exec-prefix= DIR] [ --version ] [ --libs ] [ --cflags ] DESCRIPTION
caca-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link progams, libraries, and plugins that use libcaca. The use of caca-config is deprecated. The more generic tool pkg-config should be used instead. OPTIONS
--cflags Print the compiler flags that are necessary to compile a program or library that uses libcaca. --exec-prefix=DIR If specified, use DIR instead of the installation exec prefix that libcaca was build with when computing the output for the --cflags and --libs options. This option must be specified before any of the --cflags and --libs options. --libs Print the linker flags that are necessary to link a program or library that uses libcaca. --prefix=DIR If specified, use PREFIX instead of the installation prefix that libcaca was built with when computing the output for the --cflags and --libs options. This option is also used for the exec prefix if --exec-prefix was not specified. This option must be specified before any of the --cflags and --libs options. --version Prints the currently installed version of libcaca on standard output. EXAMPLES
gcc -o main.o $(caca-config --cflags) -c main.c is how you might use caca-config to compile a C source file for an executable program. gcc -o my_app $(caca-config --libs) main.o util.o is how you might use caca-config to link compiled objects into an executable program. SEE ALSO
pkg-config(1) AUTHOR
The libcaca library was written by Sam Hocevar <sam@hocevar.net>. This manual page was written for sdl-config by Branden Robinson, originally for Progeny Linux Systems, Inc., and the Debian Project. It was adapted to libcaca by Sam Hocevar. libcaca 2003-11-22 caca-config(1)
