compiling msvcrt with gcc4

[James Hawkins]

Hi,

I just installed FC4 test1 with gcc4,

gcc (GCC) 4.0.0 20050405 (Red Hat 4.0.0-0.40)

Compiling msvcrt produces these errors:

../../../include/msvcrt/io.h:179: error: 'open' aliased to external
symbol '_open'
../../../include/msvcrt/io.h:180: error: 'sopen' aliased to undefined
symbol '_sopen'
../../../include/msvcrt/process.h:129: error: 'execl' aliased to
undefined symbol '_execl'
../../../include/msvcrt/process.h:130: error: 'execle' aliased to
undefined symbol '_execle'
../../../include/msvcrt/process.h:131: error: 'execlp' aliased to
undefined symbol '_execlp'
../../../include/msvcrt/process.h:132: error: 'execlpe' aliased to
undefined symbol '_execlpe'
../../../include/msvcrt/process.h:133: error: 'spawnl' aliased to
undefined symbol '_spawnl'
../../../include/msvcrt/process.h:134: error: 'spawnle' aliased to
undefined symbol '_spawnle'
../../../include/msvcrt/process.h:135: error: 'spawnlp' aliased to
undefined symbol '_spawnlp'
../../../include/msvcrt/process.h:136: error: 'spawnlpe' aliased to
undefined symbol '_spawnlpe'

Is this a gcc4 problem or something we can fix?

Here are a couple links that somewhat explain the problem:
