/* The -G option is ambiguous on different platforms. Sometimes it
specifies the largest data size to put into the small data
section. Sometimes it is equivalent to --shared. Unfortunately,
the first form takes an argument, while the second does not.
We need to permit the --shared form because on some platforms,
such as Solaris, gcc -shared will pass -G to the linker.
To permit either usage, we look through the argument list. If we
find -G not followed by a number, we change it into --shared.
This will work for most normal cases. */
