Hi Folks,

I have been trying to compile the latest version of gcc (2.5.2) with
little success. The build stops when the intermediate program 'enquire'
is run. Apparently enquire hangs during its run. 

I have compiled gcc on various platforms in the past including
other variants of intel based unix. I am stumped. Any idea are welcome.

Some particulars:
Machine: Gateway 2000 486/33 16Meg
OS: SCO ODT 3.0
GCC: 2.5.2 (configured as 'i486-unknown-sco3.2v4.2')

enquire is initially compiled with a bootstrap version of gcc (xgcc).
I have tried compiling enquire with cc and get the same results.
I grabed a binary version of enquire from a 386 machine w/o fpu and 
it also hangs.

The following is some output from enquire run under gdb. Once enquire
hangs I interupt it with CTRL-c. For some reason it always hangs on the
asm instruction 'flds' in fStore(). It is probably important to note
that fStore() has been called a significant number of times before
it decides to hang.
