[daip] install.pl - changing compiler options

[Vincent McIntyre]

Hi

I encountered a problem with building AIPS with the Solaris compilers,
so I wanted to change to g77/gcc.
Changing FORT, CCOM, or LINK interactively (at screen 10A) works, but
changing FORTOPT or CCOMOPT apparently does not.

I think this is because install.pl reads the input as $fo, stuffs
it into $FORTOPT or $CCOMOPT but then loops back to SCREEN_10A:,
so it never updates the displayed version of this information,
in $FORTSTR or $CCOMSTR. This means the user will get confused about
what the compiler flags are actually set to.

It looks like it should either go back all the way to SCREEN_10,
or the SCREEN_10A line should move from line 2019 to 1973 or so.
I tried the latter and it seemed to work. See patch attached.

Meanwhile, the problem with the solaris compilers seems to have gone
away...

Cheers
