I've tried to compile and install gcc-3.4.0 under Cygwin on an AMD XP and Pentium IV computer, both under Win2000. On the AMD the bootstrap succeeds with no error and I am ready to install. On the Pentium the bootstrap fails (during link?) in Stage 1 when it is unable to locate 'user32' (-luser32). user32 is located in: C: \winnt\sysstem32\user32.dll, and this is in my Cygwin PATH variable and in the Windows System PATH variable. Don't know what to do to discover what's wrong or work around the problem. Don't understand why I succeed in my home AMD computer and fail at my work pentium computer. Art
