我在编译一些软件的时候遇到一些奇怪的问题

1. 在configure的时候有时候会有这样的提示:
checking whether build environment is sane... configure: error: newly created file is older than distributed files!
Check your system clock

2. 在make的时候会有这样的提示：
doc.h:166: error: ISO C++ forbids initialization of member `LABEL'
doc.h:166: error: making `LABEL' static
chm_viewer.h:78: warning: 'backward' defined but not used
chm_viewer.h:215: warning: 'forward' defined but not used
chm_viewer.h:342: warning: 'home' defined but not used
chm_viewer.h:506: warning: 'open_f' defined but not used

第二个似乎是因为实用gcc-3.4.x的原因
