>Description:
Dear developers,

I loaded gcc-3.2 to install new c++ compiler. When I run

make bootstrap

after some work it exits with error, saying that  file
sys/ucontext.h is not found. I did not provide any flags to configure. I attached the file with the last lines of make.

Thank you for your help,

Gennady Margolin
