[bug-gettext] xgettext --from-code does not work

[jaroslav . fojtik]

Dears,

the message "please specify the source encoding through --from-code" is 
totally
frustrating, because the valid codepage is specified and it does not 
work.

================================================================
xgettext -k_ "--from-code=WINDOWS-1250" -o ref.po ../sources.cc/*.cc 
./dump.c
../sources.cc/igettext.cc:155: warning: Empty msgid.  It is reserved by 
GNU gettext:
                                        gettext("") returns the header 
entry with
                                        meta information, not the empty 
string.
xgettext: Non-ASCII string at ../sources.cc/wp2latex.cc:438.
          Please specify the source encoding through --from-code.
make: *** [ref.po] Error 1
