[Bug fortran/25494] New: error in g77 documentation (all versions)

["boschini at cilea dot it" <gcc-bugzilla at gcc dot gnu dot org>]

In particular, here:

http://gcc.gnu.org/onlinedocs/gcc-3.2.3/g77/Floating-point-Exception-Handling.html#Floating-point%20Exception%20Handling

where it states:

"...
gcc -o libtrapfpe.a trapfpe.c

and then use it by adding -trapfpe to the g77 command line when linking
..."

Whe I try it I get

/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/../../../crt1.o(.text+0x18): In
function `_start':
: undefined reference to `main'
/tmp/ccC12cnM.o(.text+0xc): In function `trapfpe':
: undefined reference to `feenableexcept'
collect2: ld returned 1 exit status



This is due to the fact that gcc does not produce an archive on the fly.

One should do:

gcc -c trapfpe.c
ar rv libtrapfpe.a trapfpe.o


Also linking is quoted incorrectly in the documentation.

It should at least be

"...-ltrapfpe..."
