/libiberty/regex.c编译错误的问题

杨志全

我的系统中编译凡有/libiberty/regex.c的程序时全部都提示错误，如：
1、In file included from ../../binutils-2.15.94.0.2.2/libiberty/regex.c:653:
../../binutils-2.15.94.0.2.2/libiberty/regex.c: In function `byte_compile_range':
../../binutils-2.15.94.0.2.2/libiberty/regex.c:4552: warning: signed and unsigned type in conditional expression
../../binutils-2.15.94.0.2.2/libiberty/regex.c:4562: warning: signed and unsigned type in conditional expression
../../binutils-2.15.94.0.2.2/libiberty/regex.c:4562: warning: signed and unsigned type in conditional expression
2、In file included from ../../../gcc-3.4.3/libiberty/regex.c:649:
../../../gcc-3.4.3/libiberty/regex.c: In function `byte_compile_range':
../../../gcc-3.4.3/libiberty/regex.c:4548: warning: signed and unsigned type in conditional expression

../../../gcc-3.4.3/libiberty/regex.c: At top level:
../../../gcc-3.4.3/libiberty/regex.c:8178: warning: unused parameter 'preg'
请教是哪里不对，这个问题对以后编译的系统有影响吗？

应该是没有影响的。我的也是常常碰到。
