Flaming printf

I agree, and do the same myself. I have LIB.L which is my usual library,
and gets searched whenever I link a program. printf,sprintf,fprintf
all reside here, and link in a normal (i.e. integer only) #doprnt which
actually does the work. All my FP stuff lives in FLIB.L, which is included
in the linkage with a -LF flag (just like UNIX :-). Now FLIB.L ALSO
contains printf,sprintf,fprintf, which also reference (and cause linkage of)
#doprnt, but the #doprnt in FLIB.L knows about floating point, and so
whenever I use printf etc. and link with a -LF, I get the right printf,
and #doprnt. LIB.L is also scanned BUT BECAUSE FLIB.L PROVIDED printf,
IT IS NO LONGER UNDEFINED, SO IT GETS BYPASSED.

Anyone who produces a linker that cannot do what I've just described needs
to talk to his analysts (both system and psycho :-)
