Hello, I have found a minor diagnostic issue.
Since r262910 we got a little odd error messages in cases like this:
$ gcc -flto-compression-level=2-O2 -c empty.c
gcc: error: argument to '-flto-compression-level=' is not between 0 and 9
$ g++ -fabi-version=2-O2 -c empty.cpp
cc1plus: error: '-fabi-version=1' is no longer supported
Old messages were more correct:
$ gcc-8 -flto-compression-level=2-O2 -c empty.c
gcc: error: argument to '-flto-compression-level=' should be a
non-negative integer
$ g++-8 -fabi-version=2-O2 -c empty.cpp
g++: error: argument to '-fabi-version=' should be a non-negative integer
When UInteger option value string is not a number, but it's first char
is a digit, integral_argument function returns -1 without setting
*err.
Proposed untested patch attached.
