Pan Chinese NT 4 Service Pack 3

Reading specs from C:\cygnus\CYGWIN~1\H-I586~1\bin\..\lib\gcc-lib\i586-cygwin32\egcs-2.91.57\specs
gcc version egcs-2.91.57 19980901 (egcs-1.1 release)

Reference to these include files have been added since 19991116 - which built
cleanly. Are they new headers that should have been introduced?

Attempting to run the testsuite using the dejagnu-19991115 snapshot
got hung up. The last reference in gdb/testsuite/gdb.log is to
(gdb) PASS: gdb.base/call-ar-st.exp: continue to 1305

Since I was able to kill the processes when run foregrounded by Ctl-C-ing
out & backgrounded by closing the Shell window, it's hard to know if this
is pointing near the offending area.
