/* Mangled into a form that works on SPARC Solaris 2 by Mark Eichin

+ * 14/8/96 based on the original gmon.c in GCC and the hacked version
+ * solaris 2 sparc version (config/sparc/gmon-sol.c) by Mark Eichin. To do

+ *
+ * Differences.
+ *
+ * On Solaris 2 _mcount is called by library functions not mcount, so support
+ * has been added for both.
+ *
+ * Also the prototype for profil() is different
+ *
+ * Solaris 2 does not seem to have char *minbrk whcih allows the setting of
+ * the minimum SBRK region so this code has been removed and lets pray malloc
+ * does not mess it up.
