AIX 由5204升级到5208时，编译c程序出错：

Syntax error at line 134, column 2, file /usr/include/standards.h:
Error at line 134, column 2 in file /usr/include/standards.h
#warning  The -qdfp option is required to process DFP code in headers.
.1
PCC-S-02014, Encountered the symbol "warning" when expecting one of the followin
g:

   a numeric constant, newline, define, elif, else, endif,
   error, if, ifdef, ifndef, include, line, pragma, undef,
   an immediate preprocessor command, a C token,
The symbol "newline," was substituted for "warning" to continue.

解决办法：

将文件/usr/include/standards.h的134行
#warning  The -qdfp option is required to process DFP code in headers.
注释掉。
