Hi,
how do I customise a specs file,
I have attached the specs file I am looking at for
my m68k-unknown-amigaos-x-i686-pc-aros gcc attempt,
I wish to disconnect -lgcc, maybe programs will link
without it,
if I replace
*libgcc:
-lgcc
by
*libgcc:
I get an error message that the specs file is malformed,
but other labels in that specs file have empty contents so why
not this one,
also I havent figured out what %D means in:
*link_libgcc:
%D
Is there a way to customise specs files?
Are there any explanations of specs files on the internet?
also not figured out what ! means,
