Re: unable to make libunicode-0.4

[Phillip J Shelton <shelton11 dingoblue net au>]

Newer glibc?  Glibc-2.1.3 is the newest on the mirror I use.  I have
also downloaded gcc-2.95.2 last night and will be installing it over the
next couple of days.

However I would like to know if any one could tell me why the following
happens.

[root frodo libunicode-0.4]# gcc -DHAVE_CONFIG_H -I. -I. -I. -W -Wall
-Wno-unused -D__restrict -c convert.c  -fPIC -DPIC -o .libs/convert.lo
In file included from convert.h:24,
                 from convert.c:28:
/usr/include/iconv.h:42: parse error before `1'

So I had a look at what the pre-processor did to the files.

[root frodo libunicode-0.4]# gcc -DHAVE_CONFIG_H -I. -I. -I. -W -Wall
-Wno-unused -D__restrict -c convert.c  -fPIC -DPIC -E |tr -s '\n' |tr -s
'\r'|uniq|less

The  pipes are to remove all the white space. Then I looked for the part
of the output that  came from /usr/include/iconv.h

# 24 "/usr/include/iconv.h" 2 3

typedef void *iconv_t;

extern iconv_t iconv_open  (__const char *__tocode,
                                __const char *__fromcode)  ;

extern size_t iconv  (iconv_t __cd,
                          __const char ** 1  __inbuf,
                          size_t * 1  __inbytesleft,
                          char ** 1  __outbuf,
                          size_t * 1  __outbytesleft)  ;

extern int iconv_close  (iconv_t __cd)  ;

The flag `-D__restrict' has tuned the word `__restrict' into a `1'!   I
do not think that this was what was wanted.
