hey all,

I use minGW5.1.4 on windows XP, and i try to use the included gcc to compile
my source codes(written in standard c), and then get a lot of "redefinition
error", i dont know why, does anybody could give me a hint?  i've searched
google for many times.
thanks!

regards,
J.Y.

Hi,
That's strange, stdio.h and math.h seems to be included twice, which
should not be possible with header guards.

Are you using the latest versions of w32api and mingwrt? If so, is is
possible to post the uncut errors? There seems to be more.

hey, it's ok when i complie my source code "file by file", one of my source
code file have a large static array there, so i guess too huge files
together make gcc crazy.
