return "?";
+ # elif defined __osf__
+ extern char** __Argv;

# else
I came to this by:
1: Looked in old gcc to find:
#define MD_STARTFILE_PREFIX "/usr/lib/cmplrs/cc/"
2: grep/nm/dis there.

There is also maybe "auxv" stuff.
I find the proc file system kinda gross and inefficient but yeah.
Thank you,
