4.1 Print required compiler flags
=================================

'gpg-error-config' is a tool that is used to configure to determine the
compiler and linker flags that should be used to compile and link
programs that use Libgpg-error.

   This tool is now obsolete.  Instead, please use pkg-config with
gpg-error.pc for your new program, or use gpg-error.m4 which uses
gpgrt-config and gpg-error.pc internally.

'gpg-error-config' accepts the following options:

'--mt'
     Provide output appropriate for multithreaded programs.  '--mt' is
     only useful when combined with other options, and must be the first
     option if present.

'--version'
     Print the currently installed version of Libgpg-error on the
     standard output.

'--libs'
     Print the linker flags that are necessary to link a program using
     Libgpg-error.

'--cflags'
     Print the compiler flags that are necessary to compile a program
     using Libgpg-error.

'--prefix=PREFIX'
     If specified, use PREFIX instead of the installation prefix that
     Libgpg-error was built with when computing the output for the
     '--cflags' and '--libs' options.  This option is also used for the
     exec prefix if '--exec-prefix' was not specified.  This option must
     be specified before any '--libs' or '--cflags' options.

'--exec-prefix=PREFIX'
     If specified, use PREFIX instead of the installation exec prefix
     that Libgpg-error was built with when computing the output for the
     '--cflags' and '--libs' options.  This option must be specified
     before any '--libs' or '--cflags' options.
