compilation error /usr/include/_G_config.h:29: parse error before "__mbstate_t"

[Vittal]

Hello All,

I am trying to compile my application on Red Hat Linux 8 against gcc
3.2.2.

Very first file in application is failing to compile. I tried
compiling my application on Linux 7.2 against gcc 3.1 and it got build
without any problems.
However on against gcc 3.2.2 I hitting this error:

gcc -DNULL="((void *)0)" -O2 -c -fPIC -D_UNIX_ -Dlinux_i32
-Dlinux_ia64 -DNEED_XMU -DX_USEBFUNCS -Dindex=strchr -DULONGDEFINED

/usr/include/gconv.h:164: parse error before '}' token
/usr/include/gconv.h:172: field `__data' has incomplete type

However I tried to reproduce the problem in a small C program, but
could not.

Can somebody help me or direct me to the path to solve this problem.

Any help is greatly appreciated.

Thanks

Probability that anything in /usr/include is bad is very close to zero. Usually
errors attributed to an included file are really errors before the #include,
such as a missing semicolon or a #define of a name the included file had
reserved unto itself.

So basically, you just trace.

Failure to compile due to syntax errors in system include files
often indicate a failure to include a prerequesite include file
beforehand. The syntax error is often something that should
be a typedef but isn't. __mbstate_t looks like a name for
a typedef. For example, in UNIX programs, you commonly need
to include <sys/types.h> before including anything of the form
<sys/*.h>.

Note that from the file paths given, <stdio.h> is an entirely
different file for the two versions of GCC.
