libio testsuite: timeout compiling tFile.cc

[John David Anglin]

The following failure in the libio testsuite occurs occurs on my machine
(a 735) because of a timeout while compiling tFile.cc:

Running ../../../../libio/testsuite/libio.tests/tFile.exp ...
Executing on host: /xxx/gnu/gcc-2.96/objdir/gcc/xgcc -B/xxx/gnu/gcc-2.96/objdir/gcc/ ../../../../libio/testsuite/../tests/tFile.cc  -O3 -I.. -I../../../../libio/testsuite/..  -nostdinc++ -I/xxx/gnu/gcc-2.96/libstdc++ -I/xxx/gnu/gcc-2.96/libstdc++/stl -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libstdc++ -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libiberty  -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libiberty -g  -lstdc++ -liberty -lm   -threads -o /xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/libio/testsuite/tFile    (timeout = 300)
WARNING: program timed out.
compiler exited with status 1
FAIL: tFile.cc compilation 

I ran the compilation manually and it does complete successfully.  However,
the resources needed to compile tFile are now quite large and can cause
vm thrashing on older machines with limited memory.  The user and sys times
for the compilation with 2.96 were:

user    9m41.150s
sys     0m57.850s

The virtual memory required by cc1plus was approximately 65MB at its peak.

In any case, I think the timeout values need to be increased for the
three tFile.cc compilations in tFile.exp unless the performance of cc1plus
can be improved.
