Thanks for the gentle hint. Initially, I get the following functions output:
defaultpapername
defaultpapersizefile
paperdone
paperfirst
paperinfo
paperinit
paperlast
papername
papernext
paperprev
paperpsheight
paperpswidth
paperwithsize
systempapername
systempapersizefile
the above functions should have static scope
and the following from the first sort -u result:
^__.*$
^main$
^psdimension$
^unitfactor$
^usage$
So everything seems correct (the files in the second extract are static;
the rest are not).
After some rummaging, I found the problem. The following pipeline:
grep -h -A1 '^extern .*[^;]$$' $$src \
| grep -vE '^(extern |--)' | sed 's/ .*//'
was coming up with an empty line, by making:
extern _GL_ATTRIBUTE_CONST const char* defaultpapersizefile(void) {
return PAPERCONF;
into an empty string. This was then later -v-matching every line of a list
of functions, and hence no error was generated.
I guessed at this point that I was supposed to do GNU-style declarations.
Bingo!
There's nothing in the documentation about this assumption, AFAICS.
