--enable-cstdio

This is an abbreviated form of '--enable-cstdio=stdio' (described next). -

--enable-cstdio=OPTION

Select a target-specific I/O package. At the moment, the only - choice is to use 'stdio', a generic "C" abstraction. - The default is 'stdio'. This option can change the library ABI. +

--enable-cstdio=OPTION

Select a target-specific I/O package. The choices are 'stdio' + which is a generic abstraction using POSIX file I/O APIs + (read, write, + lseek, etc.), and 'stdio_pure' which is similar + but only uses standard C file I/O APIs (fread, + fwrite, fseek, etc.). + The 'stdio_posix' choice is a synonym for 'stdio'. + The default is 'stdio'. This option can change the library ABI.

--enable-clocale

This is an abbreviated form of '--enable-clocale=generic' (described next).
