>Description:
The conversion to build libf2c as a shared library attempts
to link all component object files into a shared library
with one command.  Between the command arguments and
environment variables, this can overflow the maximum
argument area and definitely is larger than the arg area
required for POSIX-compliant systems breaking the GCC
bootstrap on POSIX systems.
>How-To-Repeat:

>Fix:
Create archive of intermediate directories (libF77, libI77,
libU77) and link archives into shared library.
