(programs are below) I did a few more tests and this is not a regression. OpenWatcom FORTRAN also doesn't work in FreeDOS 1.3 on the Pocket386. (Although OpenWatcom C does work with FreeDOS 1.3 on the Pocket386.)
Config 1: Reinstalled with FreeDOS 1.3 -- base system, then installed Watcomf and Watcomc. Also installed BCC, just because. Booted the Pocket386 with the default boot option. Compiling a simple "Hello world" C program with OpenWatcom worked. Compiling the same C program with BCC also works fine. Compiling a simple "Hello world" F77 program with OpenWatcom failed with this error: DOS/4GW error (2001): exception 07h (device not available) at 150:004BCAEA TSF32: prev_tsf32 5278 SS 158 DS 158 ES 158 FS 0 GS 20 EAX 526AFE EBX 532080 ECX 526AFC EDX 52FF02 ESI 526B2C EDI 527B58 EBP 0 ESP 53C54C CS:IP 150:004BCAEA ID 07 COD 526AFE FLG 10202 CS= 150, USE32, page granular, limit FFFFFFFF, base 0, acc CF9B SS= 158, USE32, page granular, limit FFFFFFFF, base 0, acc CF93 DS= 158, USE32, page granular, limit FFFFFFFF, base 0, acc CF93 ES= 158, USE32, page granular, limit FFFFFFFF, base 0, acc CF93 FS= 0, USE16, byte granular, limit 0, base 14, acc 0 GS= 20, USE16, byte granular, limit FFFF, base 2E30, acc 93 CR0: PG:1 ET:1 TS:0 EM:1 MP:0 PE:1 CR2: 0 CR3: 6067 Crash address (unrelocated) = 1:0003EAEA Config 2: Reinstalled with FreeDOS 1.4 -- base system, then installed Watcomf and Watcomc.

I forgot to save the output with Logger, but I took a photo. It has this error: Exiting due to signal SIGNOFP Coprocessor not available at eip=008acd60 ..and then the eax, ebx, ecx, edx, esi, edi, ebp, esp register values. The program was CC1.EXE Also: In 2019, someone else on Vogons reported the same "exception 07h (device not available)" error. That was in a discussion about a board without a coprocessor, and the person wrote the error is "related to the FPU according to the information I was able to find. This message disappears with the 387 installed, therefore it seems to work in some way." https://www.vogons.org/viewtopic.php?t=68057 I'm convinced this issue with OpenWatcom FORTRAN is due to the Pocket386 having a 386SX-40 CPU, without a math coprocessor.
