+ This code segment will interface between the startup code and the user's
+ main(), adjusting the stack if necessary. Two entry points are provided,
+ main(), and stkexit(). Programs should be compiled using
+     gcc -Dmain=stkmain -Dexit=stkexit
+ and linked with this module.  Calling _exit is not provided for, but should
+ be trivial to implement.
+
+ The minimum acceptable stack size is obtained from the environment variable
+ GCCSTACK (change the #define ENVNAME to customize). If this variable is
+ not defined, the default is 50000 bytes (change the #define SIZE to
+ customize). If the current stack size is less than the minimum acceptable,
+ then a new stack is allocated, and appropriate actions are taken to ensure
+ that the original stack is restored before exit.
+
+ To link with my stderrfix hack, you will need to compile it using
+        gcc -Dmain=stkmain -c stderrfix.c
+ and compile everything else (apart from this file) using
+        gcc -Dmain=mymain -Dexit=stkexit
+ (I have not tested this, but there is no reason why it shouldn't work.)
+
+ AUTHOR:     Kriton Kyrimis ([e-mail])
+ KNOWN BUGS: Calling stkexit(0x8000000) will cause the program to exit
+             with the wrong exit code (0).
+ DISCLAIMER: Use this code at your own risk.
