BTW, while grepping for 'main', 'MAIN', etc. I found some interesting
things in f-lang.h. Does anybody know what's up with these?
I coundn't see any uses or ChangeLog entries related to them.
extern char *real_main_name; /* Name of main function */
extern int real_main_c_value; /* C_value field of main function */
#define DEFAULT_DOTMAIN_NAME_IN_MF77 ".MAIN_"
#define DEFAULT_MAIN_NAME_IN_MF77 "MAIN_"
#define DEFAULT_DOTMAIN_NAME_IN_XLF_BUGGY ".main "
#define DEFAULT_DOTMAIN_NAME_IN_XLF ".main"
Also there is a "main" hack in hp-psymtab-read.c and hp-symtab-read.c
But that's local.
