--- Comment #23 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
I have modified gcc.texi here to yield, after make info, the following pasted
out of my terminal viewing with info:
‘-x LANGUAGE’
Specify explicitly the LANGUAGE for the following input files
(rather than letting the compiler choose a default based on the
file name suffix). This option applies to all following input
files until the next ‘-x’ option. Possible values for LANGUAGE
are:
c c-header cpp-output
c++ c++-header c++-system-header c++-user-header c++-cpp-output
objective-c objective-c-header objective-c-cpp-output
objective-c++ objective-c++-header objective-c++-cpp-output
assembler assembler-with-cpp
ada
d
f77 f77-cpp-input f95 f95-cpp-input
go
Note that ‘-x’ does not imply a particular language standard. For
example ‘-x f77’ may also require ‘-std=legacy’ for some older
source codes.
‘-x none’
Turn off any specification of a language, so that subsequent files
are handled according to their file name suffixes (as they are if
‘-x’ has not been used at all).
I think I will change that sentence in the parens for -x none while I am at it.
It should simply be (as if '-x' has not been used at all).
