Just tried upgrading an i386-sysv3 (ESIX SysV R3.2) from 2.2.2 to
2.3.2 using patches downloaded from ftp.uu.net.  At the end of the
phase 1 build, "enquire" fails leaving the error message "***
Unexpected signal at point 19" at the tail of float.h.

I backed off to 2.3.1.  Same result.  I tried compiling with pcc
instead of the 2.2.2 gcc.  Same result.

Here's the compile of enquire.o:

./xgcc -B./  -DIN_GCC   -g     -DNO_MEM -DNO_STDDEF -DNO_LONG_DOUBLE_IO -O0 -I. -c ./enquire.c

Enclosed is a bt from running enquire under gdb:

I haven't a clue as to where to start looking for the problem.  If you
need any more documentation, please let me know.
