>Description:
../gcc/configure:
....
checking floating point format... configure: error: Unknown floating point format
Configure in /export/home/ask/build/gcc-build/gcc failed, exiting.

gcc/config.log finished with:
configure:1857: checking execution character set
configure:1908: checking floating point format
configure:1935: gcc -c -g -O2  conftest.c 1>&5

conftest.o is in the attachment, but I guess the problem
is because of grep on binary file.

`man grep' said about it:
NOTES
  /usr/xpg4/bin/grep
     The results are unspecified if  input  files  contain  lines
     longer than LINE_MAX bytes or contain binary data.  LINE_MAX
     is defined in /usr/include/limits.a.

>How-To-Repeat:

>Fix:
Do not use just grep on binary files, use instead
strings conftest.o|grep 'format::.@IEEEF.::tamrof'
