Yes, running bootstrap is slow. One hour however indicates you using a
"not necessarily fast" machine.

Use CFLAGS_FOR_TARGET instead of CFLAGS_FOR_BUILD or add
-D__EXTENSIONS__ to CPU_CFLAGS in make/custom/Solaris-posix.cfg.

Theoretically yes, but you won't get far .. 

Building unix/posix for Solaris2.7 rsp. SunOS5.7 is known to be broken
for quite a while and fixing it doesn't have a high priority.

For lucky circumstances, building unix/posix under Linux is not
affected, building under Cygwin is affected for some versions of Cygwin,
but not all.
